/* a3d.css - Animal 3D Models UI: tokens, bar, stage, glass panels, controls, labels, sheet, toast, ad bar. UI track. ASCII only.
 * Chrome (bar, footer, ad bar) uses the habitat cream palette; everything on the stage is frosted dark glass.
 * Contrast: panel text #f3f7f2 on the glass over the darkest-to-lightest stage (#0c2326 .. #173f3a) is above 13:1,
 * muted #b9d1cc is above 8:1; pressed controls are dark ink #06201f on #e9f7f3 (15:1); the WebGL pixels cannot be
 * audited, so every label that sits on the model is on an opaque-enough dark pill (checked by tools/browser-check.js).
 * Per-animal accents arrive as --a3d-accent / --a3d-accent2 / --a3d-bg / --a3d-bg2 on body[style]. */
