/**
 * The demo video's palette, taken from the operator's studio skin (operator, 2026-10-14: "the video color scheme
 * should take the lead from the wicked skin by default"). The skin is the `studio.appearance` blob crew stores
 * verbatim (crew#323): a theme id and an HSL accent. Each theme's ground and ink are studio's own token values
 * (`src/styles/tokens.css` and `src/styles/themes/*.css`; an alpha ink is composited onto its canvas), and the accent gets the same per-theme adjustment the
 * theme applies, raised or lowered until it reads on the canvas (≥ 3:1). Renderers (garden's demo stage,
 * interactive's re-cuts) read this; an explicit brand colour of a storyline or a custom video style overrides it.
