/* Shared chrome for the preview pages, aligned on the RAGT brandbook.
 *
 * The art direction is transcribed from `template/brandbook_template.html` and
 * its stylesheets — the real site's own numbers, not our interpretation:
 *
 *   topbar     fixed, 16px inset; the nav is a floating WHITE card,
 *              max-width 1408, height 88, radius-m, shadow-xl,
 *              padding 0 24 0 32; content sits 104px below
 *   body grid  max-width 1216, padding 0 32, `240px 1fr`, gap 64
 *   side rail  sticky at 120px, red-600 kicker, Oswald title,
 *              13/20 links neutral-600 -> neutral-900
 *   footer     neutral-900, 96px top padding, neutral-800 hairline
 *   hero       red 34x2 rule, kicker at .3em tracking, Oswald uppercase title
 *
 * Colours go through this project's own tokens rather than being copied — and
 * that matters more than provenance: the brandbook's published CSS is STALE in
 * places. Its Yellow ramp is out of sync at every step and several of its
 * line-heights differ from the Figma file (see « Divergences avec le brandbook »
 * in the README). Pulling colour from `--palette-*` means this page shows the
 * current Figma values, not the brandbook's.
 *
 * Only the layout metrics, shadows and motion below are literals taken from the
 * brandbook — it carries them and the Figma variables do not. Those are not
 * colours and nothing suggests they have drifted.
 *
 * This is the page frame, not part of the shipped design system: the components
 * live in dist/ragt-components.css. */
