/*
 * CrushIt Support - design system.
 *
 * BRANDING LIVES IN ONE PLACE: the :root block. Every colour below is a var()
 * reference, so rebranding is those values and nothing else. Seeded from the
 * CrushIt app icon (teal #0f7a65) until the official hexes arrive.
 *
 * Design intent: a support console, not a landing page. Colour carries meaning
 * rather than decoration -- greys do the layout, teal marks the one action worth
 * taking, and red/amber mean a queue needs attention. Density is deliberate: an
 * agent working an exam-season backlog needs to see fifteen chats at once, not
 * five padded cards.
 *
 * Both schemes are styled. Agents work nights around exam season and a
 * hardcoded light theme is genuinely painful at 3am.
