Runtime art

The runtime-art half (src/) is what a game imports: procedural THREE.js geometry and SVG card art, built entirely in memory. No credentials, no network calls at generation time, no Blender — this half never touches the authoring pipeline's integration boundaries.

It is the extracted asset layer of the browser RTS Potyczka (races: humans / dwarves / elves / skeletons), and its APIs keep that game's vocabulary.

Modules

Module	Subpath	What it builds
`anatomy.js`	`./anatomy`	`makeBody(team, raceKey, armorTier, weaponTier, klass, magicType, weaponStyle)` — lathe-profile humanoid bodies with race visuals (skin/helmet colors, proportions, beard/ears/skull accessories); `buildBlobBody` — marching-cubes blob bodies with generated skin textures
`sculpt.js`	`./sculpt`	`sculptHumanoid(opts)` — a single-geometry vertex-colored warrior (torso/head/limb rings, face features, axe, armor details, cape, horns); palette via `opts.skin/armor/helmet/pants/boot/belt/collar/gauntlet`, plus `beard`, `eyeGlow`, `noHorns`
`sculpt-gear.js`	`./sculpt-gear`	low-level mesh helpers: `addBox`, `buildAxe`, `buildArmorDetails`, `buildBodyDetails`, `buildExtraDetails`, `buildCape`
`card-art.js`	`./card-art`	`cardArtSvg(card, race)` — a complete `<svg>` string; dependency-free
`loader.js`	`./loader`	procedural-only stubs of a former GLB loader API (see below)

three (>= 0.160.0) is a peer dependency of the geometry modules. anatomy.js additionally imports MarchingCubes from the three examples CDN and ../../lib/weapons.js — a game-side file, so ./anatomy resolves as an import only inside a host that provides that layout; sculpt.js, sculpt-gear.js, card-art.js, and loader.js are self-contained.

Card art

cardArtSvg(card, race) is pure string assembly (no DOM, runs in Node):

race picks a palette and background scene (castle, peaks, forest, ruins); unknown races fall back to humans.
card.tier picks the glow (common, combo, rare; anything else gets a neutral grey).
The glyph is chosen from card.id / card.klass / card.kind by pickGlyph (e.g. d_forge → anvil, klass: archer → bow, kind: building → tower; final fallback sword) and referenced as an <image href="<ART_BASE>/<glyph>.svg"> from assets/cards/ — overridable in a browser via window.CARD_ART_BASE.

Executed evidence: node docs/examples/card-art.mjs writes a 5.6 kB SVG.

Loader stubs

loader.js keeps the old GLB-loading API alive as explicit no-ops, because all character geometry is procedural now: loadHumanoid() resolves null, isHumanoidReady()/isRaceReady() return false, loadRaceModel() rejects with procedural-only, buildRaceUnit/buildHumanoidUnit/playClip return null, crossFadeTo returns the current action unchanged.
