+| Ink | `#0b0b0c` | line work and the figure's contour |
+| Paper | `#efe9dc` | the figure (the lion's silhouette) |
+| PrintCraft green (app colour) | `#12a58a` | the full-bleed field |
+
+**Tile:** `viewBox="0 0 512 512"`, a rounded square with `rx=112` that clips everything. Windows and Linux
+icons use the full-bleed tile. macOS icons put it on Apple's grid (an 824 px body centred on a transparent
+1024 px canvas).
+
+**Provenance:** the project owner's original drawing, made in ArtCraft (2880 px, keyed to the palette), then
+vectorised with craftrules `assets/logo-options/_tools/vectorize_tile.py` (potrace; no filtering or
+warping). The source drawing is kept in craftrules at `assets/app-icons/printcraft/source.png`, not here.
+Licence: [LICENSE.txt](LICENSE.txt) (`MIT OR Apache-2.0`, like the repo).
+
+## Files
+
+| File | What it is |
+|---|---|
+| `printcraft.svg` | the master vector (traced at 2048 px); every PNG, `.ico` and `.icns` is rendered from it |
+| `printcraft-small.svg` | a lighter vector (traced at 1024 px) for places where size matters, such as this README |
+| `printcraft-1024.png` | 1024 px on Apple's grid; also the runtime Dock icon on macOS |
+| `printcraft.icns` | macOS icon (16–1024 px) |
+| `printcraft.ico` | Windows icon (16–256 px), embedded in `printcraft.exe` by `apps/printcraft/build.rs` |
+| `hicolor/<n>x<n>/apps/ai.storyteller.printcraft.png` | Linux hicolor theme, 16–512 px; the 256 px one is the runtime icon on Windows and Linux |
+| `hicolor/scalable/apps/ai.storyteller.printcraft.svg` | Linux scalable icon (copy of the master) |
+
+Where it shows: `apps/printcraft/src/main.rs` sets the window icon (Dock, taskbar, Alt-Tab, launcher) and the
+Wayland app id `ai.storyteller.printcraft`; `packaging/linux/ai.storyteller.printcraft.desktop` names the
+hicolor icon.
