 * Educo London — educo-theme.css (Phase G24)
 * Brand theme. Loaded AFTER main.css on every page so it wins

 *
 * ── REBRANDING = EDIT THE VARIABLE BLOCK BELOW, NOTHING ELSE ──
 * Every brand colour on the site resolves to one of these lines.
 * The SEMANTIC block (--rate-*, --cap-*) carries meaning
 * (traffic-light ratings, capacity states) and must NOT be
 * rebranded — red/amber/green stay red/amber/green.
