Lib Dna

1/*
2 * lib-dna.cjs — DNA registry loader + scene-token resolver.
3 *
4 * A DNA is a complete visual language (type, palette logic, motion grammar, hero
5 * orchestration) that PARAMETERIZES per scene instead of shipping fixed look files.
6 * The resolver folds in safe-zones.json's v2 scene measurements (palette / optics /
7 * lighting) and envelope.json's loudness so the compiled tokens fit THIS clip:
8 *
9 *   accent      — scene-sampled when the DNA says "scene" (clamped readable)
10 *   text shadow — contact shadow cast along the measured light direction
11 *   depth match — embed text blur follows the scene's depth-of-field
12 *   hero amp    — entrance amplitude coupled to the spoken word's loudness (RMS)
13 *
14 * Everything is read from files written by deterministic scripts — no randomness.
