+## App drawer icons
+The app drawer icons are 32x32 tiles: a tinted rounded square (`rx="4"`) with a 24x24 glyph centered on it, colored per drawer group:
+
+| Groups | Tile | Glyph |
+| --- | --- | --- |
+| Earn, Delivery & Payments | `#DEFBE6` | `#198038` |
+| Compete | `#FFF2E8` | `#BA4E00` |
+| AI, Insights | `#FFE5EC` | `#C1294F` |
+| Learn | `#E5F3FF` | `#2C5771` |
+| Connect, Community & Content | `#F6F2FF` | `#8A3FFC` |
+| Sales & Customers | `#FCF4D6` | `#8E6A00` |
+| Team & Platform | `#D9FBFB` | `#007D79` |
+
+Glyphs come from [Material Symbols Rounded](https://github.com/google/material-design-icons) (weight 600, Apache-2.0), except `copilot-portal`, `mm`, `sales-pipeline` and `discord`, which use [Tabler Icons](https://tabler.io/icons) (MIT).
+Each icon also exists as `./{file-name}.svg`; keep its `<symbol>` in `./sprite.svg` in sync, and avoid inner `id`s so symbols don't clash inside the shared sprite.
