- mock_rpi_ws281x: stub for running without RPi hardware; auto-fallback
on RuntimeError, forced via --mock flag or MOCK_LED env var
- mock mode runs web server on port 8080 instead of 80
- replace display polling with WebSocket stream (/ws/display); client
sends start/stop messages, server pushes binary RGB frames
- force-button feedback: button shows waiting state and polls until
the cycle clears the flag
- text editor UI: edit top and bottom texts with per-segment color
pickers; saved to texts.json for persistence across restarts
- bottom and top texts read from server state instead of hardcoded
- bottom text switched to _add_multi_color_node to support multi-color
- fix bottom text invisible: split scroll_all_multi_color_texts into
top (y<8) and bottom (y>=8) passes so fill_pixels does not wipe
bottom nodes before they are drawn; this also fixes force-vehicles
polling loop that stalled when the bottom node never expired
