- screen_manager/app/tile_icons.py is the single icon list (12 groups, 20 media and music icons); tools/generate_icons.py writes it into the three icon fonts of both boards and builds the editor's subset font. - Firmware 0.2.18 shows o.icon when its fonts carry the glyph, else the domain icon. The app sends the chosen icon, or Home Assistant's own mdi icon on auto. - Tile sheet gets an icon picker with search; the mockup shows the icon the screen actually draws.
