/**
 * @file
 * MLT Modern — Colour scheme bridge.
 *
 * The parent theme (flashyplus) ships colour schemes as separate stylesheets:
 * color-blue.css, color-green.css, color-yellow.css, etc. The admin picks one
 * via Appearance → Theme settings → Look'n'Feel → Color Schemes, and the
 * parent .theme file attaches `flashyplus/color-<name>` and puts the class
 * `mt-color-scheme-<name>` on the body.
 *
 * Each parent scheme defines:
 *   --mt-color-primary, --mt-color-primary-dark, --mt-color-primary-light,
 *   --mt-color-primary-contrast,
 *   --mt-color-secondary, --mt-color-secondary-dark,
 *   --mt-color-base, --mt-color-base-dark, --mt-color-base-light,
 *   --mt-color-tint, --mt-color-shade,
 *   --mt-color-dark-colored, --mt-color-colored,
 *   --mt-color-bright, --mt-color-dark
 * ...plus *-value variants (raw HSL triples like "210, 80%, 30%") used for
 * rgba alpha effects.
 *
 * This file maps those into our component variables (--mlt-*). Components
 * never reference --mt-color-* directly — they only see --mlt-*. That gives
 * us a single seam to retune the design without rewriting components.
 *
 * Loaded weight 200 so it lands AFTER whichever color-*.css the parent
 * attached (those use weight 100). CSS variables resolve at the cascade
 * level they're used, so as long as the bridge loads after the scheme,
 * our --mlt-* always picks up the active values.
 *
 * Per the architecture decision: the ACCENT is intentionally NOT mapped
 * from the parent's --mt-color-secondary. It is a fixed yellow defined
 * here so the conversion-focused CTA aesthetic survives every scheme.
 * If you need a per-site accent override, set --mlt-accent in your
 * site's local-theme.css (the parent already loads that per site).
