# Shiftfield icon and listing metadata

Identity: Shiftfield, a roguelike Minesweeper about descending through shifting
minefields. The icon carries the game's industrial mineshaft-terminal direction:
an amber mine on a split steel tile, against charcoal. A single bold shape and
wide margins keep it usable under launcher masks. No lettering is needed.

Artwork: `assets/shiftfield-icon.png`, 256 × 256 indexed-color PNG (23,952 bytes).
Downsampled and palette-optimized from the original 1254 × 1254 imagegen artwork
(1,956,228 bytes), preserving its composition and colors. Inspected the optimized
asset at native size and 16, 32 and 64 pixels; the amber silhouette and split tile
remain distinguishable. The original artwork is retained in Git history.

The optimized PNG is within soyLI's icon limit. `napplet.json` selects it for publishing as a separate
asset referenced by the manifest's `icon` tag. Vite embeds a separate 32 × 32
derivative, `assets/shiftfield-favicon.png`, as a small data-URL favicon in the
game HTML. Regenerate it from the listing icon with:

```sh
magick assets/shiftfield-icon.png -resize 32x32 -strip PNG8:assets/shiftfield-favicon.png
```

Publishing tooling computes hashes and uploads the icon; no release was published
as part of this setup.

Existing title, description, creator credits, MIT license, topics, cover and stable
publication identifier are preserved. Optional domains are storage (persistent
progress), config (host settings), and cvm (shared depth board). No domains are
required to play. Intents and archetypes remain empty because no corresponding
cross-applet integration is implemented.
