+# Gear parts (high-res)
+
+The parts laid over the detailed sprites as their gear (helmet, shoulder piece, crown, cape,
+horn, plume; `GEAR_*` and `gen_gear` in `src/gfx.rs`). Generated on 2026-11-08 with
+`fal-ai/nano-banana-pro` (`aspect_ratio: 3:2`, `resolution: 2K`, one image), the prompt in
+`batch.py`: six pieces in light neutral grey on magenta, so the game tints them (bronze, steel,
+gold; the cape red for creatures, blue for heroes).
+
+Processing (inline python, see the session): magenta keyed out, every piece cropped to its
+picture, the horn mirrored, turned into light grey (luminance x 1.25), scaled to its place in the
+gear texture (the old rects times four: helmet 96x48, shoulder 48x36, crown 80x40, cape 112x160,
+horn 28x40, plume 28x48) with hard alpha; copied to `assets/textures/gear/<part>.png`.

+PROMPT = ("A sheet of six separate equipment pieces for a dark-fantasy pixel-art game, arranged in a grid of 3 columns and 2 rows, each piece centred "
+          "in its own cell and filling most of it, all in the same style: hand-painted pixel art, crisp edges, a dark near-black outline, shading lit "
+          "from the upper left, and every piece in LIGHT NEUTRAL GREY tones only (no other colours), so it can be tinted later. The background is a "
+          "completely flat pure magenta (#FF00FF) everywhere - no frames, no grid lines, no text. The pieces, in reading order: "
+          "1. a round metal helmet seen from the front, a dome with a riveted rim, no face, no visor; "
+          "2. a single rounded shoulder plate (pauldron) seen from the front, with two rivets; "
+          "3. a crown with three pointed spikes and small round gems; "
+          "4. a long cape seen from behind, hanging down, wider at the hem, with folds; "
+          "5. a single curved horn pointing up, slightly bent to the right; "
+          "6. a feather plume, a tall bushy crest.")
