/**
 * Shared onboarding overlay styles.
 * Built entirely on the --mc-* tokens from monaco-tokens.css so any direction
 * can retheme the overlay just by overriding --mc-red / --mc-font-display /
 * --mc-paper / --mc-ink-deep etc. before mounting it.
 *
 * Owner directive (2026-07-03), supersedes ROUND4.md R4.7's full-bleed translucent
 * veil: the previous full-screen veil let the underlying page's text ghost through
 * everywhere and let the particle cloud wander behind the readable form ("les
 * particules font n'importe quoi"). The overlay is now a solid-feeling CARD anchored
 * to one side only (left on desktop, bottom on mobile) — the rest of the viewport is
 * left completely free (app.js fades #ui out + calls engine.setFigureRect with that
 * free zone, so the ambient cloud composes beside/above the card, never behind it).
 * NO backdrop-filter. --mc-ob-* tokens are dedicated (not reusing style.css's
 * --mc-page-bg/--mc-stage-ink) so this file stays self-contained per the header
 * contract above.
