Refresh README screenshots and prune controller-era references

Replace the 480x320 Panlee-era usage/bluetooth/controller PNGs with
fresh 480x480 captures of the current UI (Usage, Bluetooth, Splash).
Drop the Controller screen column entirely — that screen was removed
when buttons took over its shortcuts.

README cleanup: daemon poll cadence corrected to 60s, splash mood-
group + auto-rotation behaviour documented, "tap the logo to cycle"
replaced with the actual middle-button gesture, Lucide section
rewritten to point at tools/png_to_lvgl.js instead of the dead inline
Python+inkscape recipe, and intro line drops "touch controller" since
touch only toggles splash now. demo.gif flagged as stale (recapture is
a hardware task).

 ## Converting Lucide icons
 
-The controller screen uses [Lucide](https://lucide.dev) icons (the same icon set Anthropic uses). Icons are SVGs converted to RGB565 C arrays for LVGL.
+The UI uses a small set of [Lucide](https://lucide.dev) icons (bluetooth + battery states) converted to RGB565 / RGB565A8 C arrays for LVGL.
-
-1. Get Lucide SVGs from [github.com/lucide-icons/lucide](https://github.com/lucide-icons/lucide) (`icons/` directory)
-
-2. Convert SVG to PNG at desired size (icons are 48×48 to match the high-DPI display, hand icon is 40×40, logo is 80×80):
 
 ```bash
-inkscape icons/delete.svg --export-width=48 --export-height=48 \
+node tools/png_to_lvgl.js assets/icon_bluetooth_48.png icon_bluetooth_data ICON_BLUETOOTH_WIDTH ICON_BLUETOOTH_HEIGHT
-  --export-filename=assets/icon_delete_48.png --export-background-opacity=0
 ```
 
-3. Convert PNG to RGB565 C array:
+Default tint is white (`0xFFFFFF`), required because Lucide PNGs ship as black-on-transparent and would render invisible against the dark UI without it. Pass `--no-tint` for pre-coloured artwork (e.g. the logo). Battery icons live as RGB565A8 (alpha plane) so they blend cleanly over the splash background; the rest of the icons are baked RGB565 over the panel colour. Splice the converter output into `firmware/src/icons.h`.

-from PIL import Image
-
-img = Image.open("assets/icon_delete.png").convert("RGBA")
