# Interface icons (high-res)

Generated on 2026-11-07 with `fal-ai/nano-banana-pro` (`resolution: 2K`, one image per sheet,
`aspect_ratio: 21:9` for the 5-column sheets, `16:9` for the spells). `batch.py` holds the
prompts: the shared text below followed by the numbered icon descriptions.

```text
A sheet of game icons for a dark-fantasy dungeon strategy game, arranged in a grid of {cols} columns and {rows} rows, every icon centred in its own equal square cell and filling about 80 percent of it, all icons the same size and in the same style: hand-painted pixel art, chunky clear shapes, crisp edges, a dark near-black outline, rich but slightly muted colours, readable at small size, light from the upper left. The background is a completely flat pure magenta (#FF00FF) everywhere, also between the icons - no frames, no grid lines, no cell borders, no text, no labels, no numbers. The icons, in reading order (left to right, top to bottom):

## Processing

`tools/cut_icons.py <sheet>-raw.png <sheet> --grid 2x5` (spells `--grid 2x4`) keys out only nearly
pure magenta (violet glows stay), crops every icon, centres it in a square and scales it to 64x64
and 128x128 with hard alpha. The strips go to `assets/textures/icons/`; the game puts them into
the high-res atlases' icon cells (`HD_ICONS` in `src/gfx.rs`).
