- Replace legacy centered stylesheet with CSS variables, layout shell,
pill navigation with active state, cards, form fields, buttons.
- Restructure SPA markup (hero, page heads, scan list as tap rows).
- Shell dialog buttons use wm-btn classes for consistent styling.
- Use per-request PortalShellRenderBundle and one root shell template; drop
server-side template registry and simplify WiFiManagerServer.
- PortalAppJS: centralize chrome/form binding; fix WiFi connect polling by
stopping previous timers on view change and before new polls.
- processPortalConnect honors _cleanConnect like connectWifi.
- Remove brittle full-JSON API tests; trim test harness surface.
- README: small doc touch-up for the shell/portal flow.
Replace multi-page portal with hash-routed SPA, DFTE shell placeholders, and
data-first JSON APIs. Remove legacy routes, root-template override path, and
HTML-derived info pipeline. Add bootstrap feature flags, in-DOM toast/dialog UX,
OTA via POST /u, and tests for shell, bootstrap, API JSON, and captive host rule.
Rewrite README as fork disclaimer and modernization overview.
Replace DEBUG_WM with WiFiManagerLogLevel/log(), optional WiFiManagerLogSink,
and WM_NO_LOG stripping. Add JSON API handlers and shell templates (RootShell,
PortalAppJS). Bridge DFTE logging with owner-scoped teardown; add migrate_debug_wm
helper; document and set WM_LOG_LEVEL in platformio.
