+# PhotoCraft app icon
+
+A **nine-tailed kitsune with a brow diamond**: an engraving portrait, seated, looking back at the
+viewer, in the Crafting Apps' owl-template framing (full-bleed field, head and body filling the
+tile, tails running off the edges).
+
+## Palette
+
+Exactly three colours:
+
+| Colour | Hex | Used for |
+|---|---|---|
+| Ink | `#0b0b0c` | line work and contours |
+| Paper | `#efe9dc` | the figure |
+| PhotoCraft blue (app colour) | `#2f7bf5` | the full-bleed field |
+
+## Geometry
+
+A 512-unit tile (`viewBox="0 0 512 512"`), rounded square with `rx=112`, no border. The macOS
+renders pad it onto Apple's 824/1024 icon grid; the Windows and Linux renders crop 22 units off
+each side so the figure reads at 16–48 px.
+
+## Provenance
+
+The owner's original drawing, made in ArtCraft (2880 px, engraving style, keyed to the palette),
+vectorised with craftrules `assets/logo-options/_tools/vectorize_tile.py`. The source PNG stays in
+craftrules at `assets/app-icons/photocraft/source.png`. License: see `LICENSE.txt`.
+
+## Files
+
+- `photocraft.svg`: canonical master (traced at 2048 px).
+- `photocraft-small.svg`: lighter trace (traced at 1024 px); also the hicolor scalable icon.
+- `photocraft-1024.png`: 1024 px render on the macOS grid.
+- `photocraft.icns`: macOS bundle icon (`CFBundleIconFile`).
+- `photocraft.ico`: Windows icon, 16–256 px, embedded in the `.exe` by `apps/photocraft/build.rs`.
+- `hicolor/<size>/apps/ai.storyteller.photocraft.png` (16–512) and `hicolor/scalable/...svg`:
+  Linux icon theme.
+
+The app also sets the window icon and Wayland app ID at runtime (`apps/photocraft/src/main.rs`).
+
+## Regenerate
+
+Replace `photocraft.svg` (and `photocraft-small.svg`), then run `packaging/icons.sh`. It needs
+`resvg`, plus `iconutil` on macOS; the `.ico` is packed by `cargo xtask ico`.
