 # Changelog
 
-## 3.0.3
+## 3.2.2
+
+- Align the direct ESP8266 and ESP32 test environments with the packaged DFTE 1.2.0 dependency.
+
+## 3.2.1
+
+- Ensure externally supplied station profiles remain authoritative on ESP32 by clearing stale SDK-owned credentials before opening the portal for an empty or invalid external profile set.
+- Pin DFTE 1.2.0, the tested template-engine release used by the maintained portal.
+
+## 3.2.0
+
+- Refine the device-hosted portal with a startup Wi-Fi scan, stable loading overlays, clearer connection progress, and a resettable configuration timeout.
+- Keep a successful portal-to-station hand-off reachable until the browser acknowledges its redirect, with a bounded fallback for captive or headless clients.
+- Rename the presentation field `homeIntro` to `tagline` so portal identity and wording are clearer; update portal bootstrap contract to v3.
+- Add focused Basic Portal, Branded Portal, Custom Portal Content, and Station Profiles examples for ESP8266 and ESP32, with real-hardware README captures.
+- Strengthen release CI with documentation and clean-consumer/example compilation checks for both supported targets.
+
+## 3.1.0
+
+- Add an opt-in primary/fallback station-profile controller with bounded failover, reconnection, a durable consumer-supplied store, and profile-aware portal APIs. DeviceFramework uses this to persist verified WiFi profiles transactionally.
+- Add portable portal branding and presentation hooks, including theme-aware shell and template rendering, without requiring DeviceFramework.
+- Pin ESP32 tests to the Arduino 3-compatible pioarduino platform release and resolve DFTE 1.1.0.
+
+## 3.0.6
+
+- Correct async PlatformIO dependency owners to the registry's canonical lowercase identity, so a clean consumer builds WiFiManager and its ESP8266/ESP32 transport dependencies without duplicating them in `lib_deps`. Remove the superseded include-path bridge.
+
+## 3.0.5
+
+- Add a library-owned PlatformIO bridge for the asynchronous web/TCP include paths required when WiFiManager is nested beneath DeviceFramework.
+
 ## 3.0.4
 
 - Set the package's deep PlatformIO dependency-discovery mode so WiFiManager's asynchronous web/TCP children remain available when it is consumed through DeviceFramework.
 
+## 3.0.3
 
 - Declare the ESP8266 and ESP32 async TCP libraries explicitly in the PlatformIO package manifest so clean consumers resolve the headers required by the asynchronous portal.

 # WiFiManager
 
-This repository is a **breaking fork** of upstream [`tzapu/WiFiManager`](https://github.com/tzapu/WiFiManager).
+WiFiManager gives ESP8266 and ESP32 firmware a polished, self-hosted Wi-Fi setup experience. It reconnects to saved networks and opens a temporary captive portal when it cannot, so users can configure the device from any phone or browser without a cloud service or companion app.
-It is not a drop-in replacement for upstream behavior, APIs, templates, or portal customization patterns.
 
-If you are evaluating this fork, assume that core web-portal architecture has changed and review the code before adopting it in an existing upstream-based project.

-
+## Make it yours
-## Breaking Changes
-
-This fork intentionally modernizes and restructures the configuration portal.
-Notable differences from upstream include:
-
-- The portal now serves a **single HTML shell** from `GET /`.
-- Client navigation is handled as a **SPA with hash routing**.
-- Interactive behavior is exposed through **JSON APIs under `/api/...`** plus firmware upload at **`POST /u`**.
-- Legacy multi-page portal routes and legacy root-template override paths have been removed.
-- The portal rendering pipeline is built around **DFTE** instead of upstream's monolithic HTML string assembly.
-- JSON endpoints are expected to be **data-first**, not derived from generated HTML fragments.
-
-## Current Improvements And Modernization
-
-This fork currently includes the following architectural improvements:
-
-- A **single-shell portal architecture** with embedded bootstrap JSON and embedded application JS.
-- A **SPA-based configuration UI** for WiFi setup, parameters, info views, device actions, and OTA flow.
-- A **clean API surface** for WiFi scanning, WiFi save, parameters, info, status, restart, erase, portal exit, and captive-portal close behavior.
-- **Captive portal redirect handling** retained while removing duplicate legacy UI architecture.
-- **Data-first JSON generation** for portal APIs, including info/device/about data, instead of HTML-to-JSON parsing.
-- **Capability-driven UI flags** in bootstrap/API payloads so features like info, update, erase, and action visibility can be controlled by backend state.
-- **Portal bootstrap contract v2**: nested `brand`, `context`, `pages`, `actions`, `layout`, `extraHomeCards`; Wi-Fi meta params include `kind` (`field` | `html`) for first-class custom HTML parameters.
-- **SPA-native feedback UX** using in-DOM dialog/toast behavior rather than page-based action flows.
-- **Connect-on-save handoff**: when portal save triggers a station connect, `/api/wifi/connect-status` now reports a brief success state with `stationIp` and `redirectUrl` so the SPA can show the new address and redirect before the AP shuts down.
-- **Request-scoped shell rendering**: the root portal page is built for each `GET /` from `WM_ROOT_SHELL_TEMPLATE` using a fresh placeholder registry. Shell inputs are `%PAGE_TITLE%`, `%STYLES%`, `%BOOTSTRAP_JSON%`, `%PORTAL_APP_JS%`, and `%PORTAL_APPEND_JS%` — filled in `WiFiManagerHandlers` from WiFiManager state and embedded assets (not from a server-wide template registry).
-- **Customization via WiFiManager `portal*` APIs** (`portalSetBrandTitle`, `portalSetPageInfoVisible`, `portalSetLayoutParamsLocation`, `portalAddParameter`, asset hooks, etc.) and JSON under `/api/...`, not by exposing placeholder-registry mutation to consumers.
-- A clearer separation between:
-  - shell rendering (handlers + SPA bootstrap)
-  - JSON API responses
-  - captive portal behavior
-  - OTA handling
-- Updated tests focused on the **shell contract**, **bootstrap payloads**, and **API JSON shapes** rather than removed legacy portal pages.
-
-## Portal Customization Boundary
-
-Stable, supported portal customization is intentionally scoped:
-
-- `portalSetBrand*` for title, intro text, and logo SVG, plus `portalSetContextIdentityText(...)` for the user-facing runtime identity string on the home view.
-- `portalSetPage*`, `portalSetAction*`, `portalSetLayout*`, and `portalSetBehavior*` for built-in portal capabilities and runtime behavior.
-- `portalAddParameter(...)` for first-class custom parameters, including raw HTML blocks inside parameter-rendering surfaces (`#/wifi` or `#/setup`).
-- `portalAddInfoSection(...)` and `portalAddHomeCard(...)` for structured extra content rendered by the built-in SPA.
-- `portalAppendCss(...)`, `portalOverrideCss(...)`, and `portalAppendJs(...)` for light theming and enhancement hooks.
-
-Not part of the stable API:
-
-- arbitrary HTML injection into home/info/nav/shell
-- replacing built-in SPA routing or action flow
-- depending on undocumented DOM IDs or route internals
-- treating `include/templates/*` as a supported consumer override surface
-
-Appended JS should enhance rather than replace the built-in SPA. The documented hook contract is:
-
-- `wm:ready` with `detail.boot`
-- `wm:view-changed` with `detail.route`
-
-If a consumer needs custom live widgets, new primary navigation concepts, or new backend-to-frontend workflows, that is considered **fork territory** rather than portal customization.

-## WiFi Connect Status API
-
-When `portalSetBehaviorConnectOnSave(true)` is enabled, saving WiFi credentials queues a station join and the SPA polls `GET /api/wifi/connect-status`.

-  "message": "human readable status",
-  "wifiStatus": "WL_CONNECTED",
-  "stationIp": "192.168.1.42",
-  "redirectUrl": "http://192.168.1.42/"
 }
 ```
 
-Notes:
+The [Branded Portal](examples/BrandedPortal/) example includes a static SVG, accessible identity text, and a small semantic theme. [Custom Portal Content](examples/CustomPortalContent/) shows the supported parameters, information sections, and home cards without replacing the portal shell.
 
-- `stationIp` and `redirectUrl` are present only after a successful station join.
+## What it provides
-- If the portal HTTP server is not on port `80`, `redirectUrl` includes the active port.
-- On success, WiFiManager keeps the portal alive briefly so the client can read the success payload and navigate to the new device address before the captive AP is shut down.
-- This improves the handoff on typical home networks, but it is not a universal guarantee: client captive-portal helpers, browser behavior, DHCP timing, and network isolation can still affect whether the redirect completes automatically.
 
-## Dependencies
+- **Captive Wi-Fi setup:** starts an access point only when saved network credentials cannot connect.
+- **Responsive portal:** one small portal for Wi-Fi, application fields, information, actions, and firmware update flow.
+- **Structured APIs:** JSON endpoints under `/api/...` for applications that need portal state or connection results.
+- **Product presentation:** title, logo, tagline, and semantic colour tokens without copying the portal HTML.
+- **Primary and fallback networks:** an opt-in two-network controller backed by an application-provided store.
+- **ESP8266 and ESP32 support:** the package resolves its asynchronous web dependencies for the selected target.

+# Getting started
+
+WiFiManager owns station credential recovery and a temporary configuration portal. Keep one instance for the life of the application.
+
+```cpp
+#include <Arduino.h>
+#include <WiFiManager.h>
+
+WiFiManager wifi;
+
+void setup() {
+    Serial.begin(115200);
+    wifi.setConfigPortalTimeout(180);
+    wifi.autoConnect("Example Setup", "change-me");
+}
+
+void loop() {
+    wifi.process();  // Keeps the portal responsive when setup is needed.
+    // Normal work begins after autoConnect succeeds.
+}
+```
+
+`autoConnect()` first tries stored station credentials. If that cannot connect, it starts the AP and portal with the supplied name and password, then returns `false`; call `process()` from `loop()` so that portal can run. Use a Wi-Fi-valid AP password.
+
+## PlatformIO dependency

+# Portal API
+
+The portal uses JSON endpoints under `/api/...` for WiFi scans and saves, parameters, information, status, restart/erase/exit actions, captive-portal closure, and station-connect status. Consumers should treat the documented response shapes as the contract; portal HTML is not an API.
+
+The current bootstrap contract is version 3. It includes `brand.tagline`, the short product tagline rendered in the portal header.
+
+## Profile-mode WiFi metadata
+
+When an application supplies a `WiFiManagerStationProfileStore`, `GET /api/wifi/meta` reports a primary profile and optional fallback without returning passwords. `POST /api/wifi/save` verifies a submitted candidate before committing it; see [station profiles](STATION_PROFILES.md) for fields and lifecycle.
+
+## WiFi connect status
+
+When `portalSetBehaviorConnectOnSave(true)` is enabled, saving credentials queues a station join. The SPA polls `GET /api/wifi/connect-status`:
+
+```json
+{
+  "state": "waiting | success | failed",
+  "message": "human readable status",
+  "wifiStatus": "WL_CONNECTED",
+  "stationIp": "192.168.1.42",
+  "redirectUrl": "http://192.168.1.42/"
+}
+```
+
+`stationIp` and `redirectUrl` are present only after a successful join. If the portal server is not on port 80, `redirectUrl` includes that port. When connect-on-save is disabled, a saved configuration has no station address and the built-in portal remains open.
+
+On success, the SPA first reads the station address, then POSTs `/api/wifi/connect-complete`. WiFiManager keeps the portal available for a fallback period while it waits for that acknowledgement, then closes it after a short grace delay so the normal device web server can start. This removes the old client-side race where the portal could disappear before the final status arrived. Captive-portal helpers, DHCP timing, browser behaviour, and network isolation can still prevent an automatic redirect, so clients must retain the visible address as a fallback.
+
+## Portal timeout
+
+When a configuration-portal timeout is enabled, `POST /api/portal/timeout-reset` restarts the countdown and returns `{ "ok": true, "timeoutSecondsRemaining": N }`. The built-in overview exposes this as an explicit reset control; custom clients may use the documented endpoint too.
+
+## API design rules
+
+- Use JSON endpoint results for state and actions.
+- Keep UI-visible capabilities in the portal bootstrap/API payloads.
+- Add a documented endpoint contract before adding a new portal workflow.
+- Do not derive state by parsing the rendered shell.

+# Portal UI
+
+`WiFiManagerPortalConfig` is the supported presentation API for the built-in provisioning portal. It changes identity and semantic visual tokens only. WiFiManager continues to own portal routes, forms, navigation, captive behavior, reset, and OTA views.
+
+Apply the configuration before `autoConnect()`, `startConfigPortal()`, or `startWebPortal()`. The configuration is non-owning: text and SVG data must have static firmware lifetime and declare whether it is in RAM or PROGMEM. WiFiManager locks presentation after a portal starts, so active asynchronous responses cannot observe a partial configuration.

+
+## Configuration reference
+
+Leave a text or colour value empty, or a radius at `0`, to retain the built-in stylesheet value. The default title is `WiFiManager`.
+
+| Field | Used by |
+| --- | --- |
+| `title` | Document title and concise setup-page heading |
+| `identityText` | Company or product name in the header above navigation |
+| `tagline` | Short tagline in the header above navigation |
+| `logo.svg`, `logoAltText` | Optional trusted inline SVG and its accessible label |
+| `pageBackground`, `surface`, `text`, `mutedText`, `border` | Portal surfaces and text |
+| `accent`, `accentHover`, `accentText` | Primary links and actions |
+| `success`, `danger`, `dangerHover` | Status and destructive actions |
+| `cornerRadiusPx`, `smallCornerRadiusPx` | Card and compact-control corners, limited to 64 px |
+
+Theme values accept only simple semantic CSS value syntax and are emitted once into a small `#wm-portal-theme` block. This is deliberately not a raw CSS or JavaScript injection API. An SVG is a trusted compiled firmware asset, never form, MQTT, or network input.
+
+## Built-in portal capabilities
+
+Presentation uses one configuration route: `setPortalConfig()`. Existing structured portal capabilities remain separate: `portalAddParameter()`, `portalAddInfoSection()`, `portalAddHomeCard()`, page visibility, and portal behavior configure documented built-in functionality rather than private markup. See [Portal API](PORTAL_API.md) and [Station profiles](STATION_PROFILES.md).
+
+There is no arbitrary HTML shell, route replacement, navigation injection, raw stylesheet, or script hook. If a product needs a new portal capability, add a narrow WiFiManager contract and test it on both supported targets.

+# Station profiles
+
+WiFiManager 3.1.0 adds an opt-in station-profile controller for applications that need a primary Wi-Fi network and one fallback. It is independent of the legacy `autoConnect()` flow: existing WiFiManager consumers do not need to change.
+
+A WiFiManager application supplies its own durable store. The controller can also be used with an in-memory store for a temporary session, but credentials will not survive a restart.
+
+## Lifecycle
+
+A profile set has exactly two fixed slots:
+
+- **Primary** (slot 0) is required whenever the controller is enabled.
+- **Fallback** (slot 1) is optional.
+- The last successful slot is tried first on the next connection cycle, then the remaining enabled slot.
+
+The controller never treats the ESP SDK's saved single network as an additional source of truth. It begins one bounded connection attempt at a time, moves to the fallback after failure, and retries both profiles after a temporary loss of a previously working connection. If a new device has no valid profiles, it opens the normal configuration portal.
+
+A candidate submitted by the portal is only committed after it connects and receives a usable IP address. A failed candidate leaves the last saved profile set intact.
+
+## Direct WiFiManager use
+
+Implement a small store appropriate to the application. The manager neither allocates nor owns it:
+
+```cpp
+class MyProfileStore final : public WiFiManagerStationProfileStore {
+public:
+    bool load(WiFiManagerStationProfiles& profiles) override;
+    bool save(const WiFiManagerStationProfiles& profiles) override;
+    bool clear() override;
+};
+
+WiFiManager wifi;
+MyProfileStore profiles;
+
+void setup() {
+    wifi.setStationProfileStore(&profiles);
+    wifi.setStationRecoveryInterval(30000);
+    wifi.startStationConnection("Example Setup", "setup-password");
+}
+
+void loop() {
+    wifi.process();
+}
+```
+
+The store must return a complete `WiFiManagerStationProfiles` value. Each enabled profile has a NUL-terminated SSID of at most 32 characters and an optional NUL-terminated password of at most 64 characters. Keep slot 0 enabled; set `hasPassword = false` for an open network.
+
+To stage profiles supplied by another subsystem, use `startStationCandidate(candidate)`. It connects the primary/fallback set first and calls the store only after success. Use `saveStationProfiles(profiles)` only when deliberately saving without a connection check. `clearStationProfiles()` clears the supplied store and disconnects the station.
+
+## Portal contract
+
+In profile mode, the existing Wi-Fi page becomes a two-profile form. It remains driven by the same JSON endpoints:
+
+- `GET /api/wifi/meta` returns `profiles`, `activeSlot`, and controller `state`.
+- `POST /api/wifi/save` accepts `s0`/ `p0` for primary and `s1`/ `p1` for fallback. A blank submitted password preserves an existing password; send `clear0` or `clear1` for an intentional open network.
+- A normal save verifies the candidate by connecting. Poll `GET /api/wifi/connect-status` for its result.
+- Set `stationAction=save` only to store the submitted profiles for a later connection attempt.
+
+The portal requires a non-empty primary SSID. Its API never returns a password; it only reports whether one is set.
+
+See [Portal API](PORTAL_API.md) for the shared connection-status response. The buildable [Station Profiles](../examples/StationProfiles/) example contains a compact EEPROM-backed store for both supported ESP targets.

+# Testing
+
+The clean-consumer check builds a project that declares only WiFiManager. It proves the package manifest resolves DFTE, ESPAsyncWebServer, and the correct ESP8266 or ESP32 TCP dependency without a sibling checkout or attached board. The runner removes a previous local package link before each
+check, so dependency resolution uses the current manifest rather than a stale
+`.pio` copy.

+# Basic Portal
+
+This is the smallest useful WiFiManager application. It first tries the credentials the ESP platform already knows. If it cannot connect, it opens an access point named **WiFiManager Basic** with password **example-pass**.
+
+1. Build and flash the selected `esp8266` or `esp32` environment.
+2. Connect a phone or computer to **WiFiManager Basic**.
+3. Open `http://192.168.4.1/` if your captive-portal helper does not open it automatically.
+4. Select a network and save it. The board joins that network and the next reboot reconnects without opening the portal.
+
+The access-point password is only an example. Choose a unique, Wi-Fi-valid password for a real product.

+See the shared [example guide](../README.md) and [getting started](../../docs/GETTING_STARTED.md).

+# Branded Portal

+This example uses the supported `WiFiManagerPortalConfig` presentation API to give the built-in portal a product name, company identity, tagline, inline SVG mark, and semantic colour tokens.
+
+Flash the `esp8266` or `esp32` environment, join **Temperature Monitor**, and open `http://192.168.4.1/`. The visual changes come from static firmware data; WiFiManager still owns the portal routes, forms, validation, and captive-network behaviour.
+
+Use only trusted compiled SVG data. Keep the backing strings static for the lifetime of the firmware, then call `setPortalConfig()` before opening a portal.

+- an editable MQTT broker host field;

+It opens **WiFiManager Content** with password **example-pass** until it has working station credentials. Save the form, then inspect serial output to see the selected broker value.

+# Station Profiles
+
+This example gives WiFiManager a small application-owned EEPROM store. The portal accepts a required primary Wi-Fi network and an optional fallback, verifies a submitted network before saving it, then remembers the last successful choice across restarts.
+
+On a blank board, connect to **WiFiManager Profiles** with password **example-pass** and open `http://192.168.4.1/`. Enter a primary network and, if useful, one fallback. After a successful connection, restart the board to confirm that it tries the saved profiles before reopening the portal.
+
+`StoredProfiles` is intentionally simple so the ownership boundary is visible. A production application should add its own record versioning and integrity protection around the application’s complete configuration; WiFiManager only owns network-selection policy.
