/* The shared stylesheet for every CMS-rendered tenant website.
 *
 * LIGHT, and professional rather than decorative: a company that sells AI
 * training data is judged on looking precise, so the work here is hierarchy,
 * rhythm and restraint — not colour. One accent, one neutral ramp, generous
 * whitespace, and real visual anchors (logo, hero artwork, per-card icons) so a
 * page is never an undifferentiated wall of paragraphs.
 *
 * The class names ARE the contract with lib/cms/site-renderer.js. Change one
 * here and change it there, or a band silently loses its styling.
 *
 * Per-tenant colour can be overridden later from globalContent without touching
 * this file; the palette is entirely custom properties for that reason. */
