- Move SPEC-old.md, PLAN.md, TODO.md -> docs/ (migrationshistorie
nachvollziehbar, nicht geloescht laut Auftrag)
- README.md neu: WT32-SC01-Plus-Setup, Touch-Bedienung, Projektstruktur,
Verweis auf m5stack-dashboard als Referenz
- deploy.sh unverändert (hardwareunabhaengig, ruft nur pio run --target
upload auf)
- src/icons/icons.{h,cpp}: colored procedural icons drawn onto LVGL
canvases (PSRAM-backed ARGB8888): sun, moon, cloud, rain, thunderstorm
(selected from API symbol field), rain-warning triangle, retry/error
symbol, back arrow. Replaces old M5GFX-based icons.h.
- tile_button: add tile_button_set_icon_obj() to swap text glyph for a
canvas icon object
- home_screen: weather tile now shows the real procedural weather icon
(rebuilt on each refresh); tapping the weather tile in error state
triggers a manual retry (SPEC.md section 8) instead of navigating
- weather_detail: scrollable hourly forecast (time, temp, description,
rain probability), data logic ported from old weather_detail_screen.cpp
- calendar_detail: scrollable list of all 10 events (summary + formatted
date/all_day), ported from old calendar_detail_screen.cpp
- mvg: scrollable departures list (line badge U/S colored, destination,
time/delay, cancellation), 1-minute refresh timer ported from old
mvg_screen.cpp
- all three use back_button widget (fixed bottom-left)
- main.cpp: Screen controller, navigates between screens via callbacks,
5-minute inactivity timeout -> home, per-screen tick() for refresh
