/*
 * Bright Minds — canonical brand design tokens (SINGLE SOURCE OF TRUTH).
 * ---------------------------------------------------------------------------
 * Change a brand value HERE and nowhere else. Consumed by:
 *   • the static marketing site (root *.html + assets/site.css)
 *   • the archived manuals (archive/thebook, archive/portal-manual-web)
 *   • the future bml-portal app (imported via @brightminds/brand — see brand/README.md)
 *
 * Plain CSS custom properties → usable with ZERO build (static HTML via <link>),
 * and by Tailwind (see brand/tailwind-preset.js). Both a hex value and an
 * "R G B" triple are provided per color: the triple powers Tailwind's
 * `rgb(var(--x-rgb) / <alpha-value>)` pattern so opacity modifiers keep working.
