+# Creature sprites in the imp's style (fal.ai)
+
+Generated on 2026-11-07: one idle sprite sheet per creature kind of `SPRITE_KINDS` in
+`src/gfx.rs` (all except `EK::Worker`, the imp, see `../imp-sprite/`), in the style of the imp's
+`raw-1.png` lower row. Each creature has `<id>-32.png` (160x32) and `<id>-64.png` (320x64): five
+views side by side (front, front three-quarter turned right, side facing right, back
+three-quarter turned away to the right, back), transparent, one palette per sheet, feet (or the
+lowest pixel) on the bottom row, the tallest or widest view filling the cell. Ids are the
+`unit.<id>` keys; `manifest.json` maps them to the `EK` variants with a quality note.
+
+## Generation
+
+- Model: `fal-ai/nano-banana-pro/edit` (POST https://fal.run/fal-ai/nano-banana-pro/edit)
+- `aspect_ratio: 21:9`, `resolution: 2K`, `num_images: 1`, `output_format: png`
+- Reference image (`image_urls`, as a data URI): `style-ref.png` = the lower row of
+  `../imp-sprite/raw-1.png` (crop fractions 0,0.27,1,0.72) scaled to 1600 px wide, the dark
+  cell frame lines painted over with magenta (the kobold, the first request, still had a
+  reference with frame lines and copied them).
+- Background: flat magenta, flat green (#00FF00) for the purple creatures (spider, mage, bat, trader).
+- 34 images: 30 creatures + 4 retries (spider, dwarf, revenant, ram; each had the wrong
+  number or order of views). For dwarf and ram the retry gave the missing back three-quarter
+  view but lost another one, so both tries are combined. About $5 at ~$0.15 per 2K image.
+- Scripts in `scripts/`: `creatures.py` (descriptions, prompt template), `gen.py` (requests,
+  4 at a time; reads the key from `~/.config/dungeoncraft/fal-key`), `compose.py` (sets chosen
+  figures of one or more raw sheets into one new row), `process.py` (runs the pixelize tool for
+  all creatures with the arguments of `extra.txt`).
+
+Even with "exactly five figures in one row" in the prompt the model often drew two rows (mostly
+two copies of the five views, then the top row is used with `--crop 0,0,1,0.5`) or skipped
+the back three-quarter view.
+
+### Prompt template
+
+`{thing}` is `creature` or `siege engine`; `{pose}` is `standing, idle`, `hovering in the air,
+idle` (bat, gargoyle, owl, wyrm, fairy) or `standing still` (ram, catapult); `{bgname}` is
+`magenta (#FF00FF)` or `green (#00FF00)`. The kobold and the first spider request were sent
+without "exactly five figures in one row (no second row, no extra figures)," (the layout line
+read "the same five views in one single horizontal row,").
+
+```text
+The attached image is the style reference: a pixel art sprite sheet of the "Pit Imp" in five views (left to right: front, front three-quarter turned right, side facing right, back three-quarter turned away to the right, back).
+
+Draw a DIFFERENT {thing} in exactly the same style: the "{name}". {desc}
+
+Use exactly the same style as the reference: the same compact chibi proportions (big head, short stocky body, about the same overall size as the imp), the same thick one-pixel near-black outline, the same palette approach (flat colours with one highlight and one shadow tone), the same pixel size (about 32x32 pixels per figure, scaled up with hard square pixels), no anti-aliasing, no gradients, no blur.
+
+Layout: exactly five figures in one single horizontal row (no second row, no extra figures), the same five views, in the same order (1 front view facing the viewer, 2 front three-quarter view turned to the right, 3 side view facing right, 4 back three-quarter view turned away to the right, 5 back view), evenly spaced, all the same size, {pose}, each figure separated from its neighbours by empty background.
+
+Background: flat pure {bgname} everywhere, no ground, no shadows, no text, no labels, no frames, no grid lines, no cell borders.
+```
+
+Retries (dwarf, revenant) appended:
+
+```text
+Important: there must be exactly FIVE figures in ONE row. Do not skip the fourth one: the back three-quarter view, seen from behind at an angle, the face hidden, the body turned away from the viewer towards the upper right, between the side view and the straight back view.
+```
+
+The ram retry appended instead:
+
+```text
+Important: there must be exactly FIVE drawings of the machine in ONE row, no second row. 1 front view: the iron-capped end of the ram points straight at the viewer. 2 front three-quarter view: the capped end points towards the viewer and to the right. 3 side view: the capped end points to the right. 4 back three-quarter view: the capped end points away from the viewer towards the upper right, we see the rear end of the machine. 5 back view: we see the rear end straight on.
+```
+
+## Pixel grid
+
+`tools/pixelize_sprite.py` (Pillow: `/tmp/sprvenv/bin/python -I`), from the repo root:
+
+```bash
+T=tools/pixelize_sprite.py
+python $T art/generated/sprites/<id>-raw.png art/generated/sprites/<id> --views 5 --size 32 --colors 16 --feet 31 --outline-weight 0.6 [extra]
+python $T art/generated/sprites/<id>-raw.png art/generated/sprites/<id> --views 5 --size 64 --colors 24 --feet 63 --outline-weight 0.6 [extra]
+```
+
+(the tool also writes `<id>-<size>-preview.png`; those were deleted). `[extra]` per creature is
+listed below. Composed raws were made first with `scripts/compose.py` (run from `scripts/`).
+
+### Tool changes (backwards compatible)
+
+- Background key `--bg auto` (default): the key colours are sampled from the sheet's border and
+  only colours close to them (and their blends with the dark outline) are removed, so purple
+  creatures on green survive; `--bg magenta` is the old fixed test, `--bg R,G,B` an explicit key.
+- Blends of the key colour with thin figure parts (pinkish edge pixels on a spear) get no vote.
+- Frame/grid lines (a column or row at least 97% one flat non-background colour) are removed,
+  plus their anti-aliased edges.
+- `--split auto` (default): figures are found by the empty columns between them, else by
+  connected parts, else by cutting touching figures at their thinnest column, else equal cells
+  (`--split cells`, the old behaviour); small pieces of a neighbour at a cell edge are dropped.
+- `--row-counts 4,3` (rows with different numbers of figures) and `--pick 0,1,2,m5,3` (build
+  the output row from chosen figures, `m` mirrors).
+- Single pixels without any neighbour are removed (`--no-despeckle` keeps them).
+- The imp's `raw-1.png` gives the same sheet as before (42 of 5120 pixels differ in coverage).
