/**
 * Facet — main stylesheet.
 *
 * THIS FILE NEVER NAMES A COLOUR, A FONT OR A SIZE. Every value comes from a
 * --fct-* custom property compiled by inc/dynamic-css.php from the active
 * preset. That constraint is what makes five genuinely different-looking
 * presets maintainable from one codebase: there is no "dark mode branch", no
 * per-preset override block, and no place for one preset to drift.
 *
 * If you find yourself wanting to add `.preset-tech .foo { ... }`, add a token
 * instead.

/* ------------------------------------------------------------------ *
 * 13. Ambient field
 *
 * A fixed WebGL layer (assets/js/ambient.js) sits behind the whole
 * document. For it to be visible at all, the surfaces stacked on top of
 * it have to stop being fully opaque — but they cannot simply become
 * transparent either, because body text sits on them and the contrast
 * work in inc/dynamic-css.php is measured against the background token.
 *
 * So the veils below are deliberately heavy. The ambient field reads as
 * a slow drift of colour and light THROUGH the page rather than as a
 * picture behind it, and every text-bearing surface keeps enough of its
 * own background to hold its measured contrast. The shader's amplitude
 * is bounded to match; the two halves of this are a pair.
 *
 * All of it is scoped to .has-ambient, which ambient.js only adds once
 * the layer is actually running. No canvas, no changes — the flat
 * fallback stays exactly as it was.
