/* ============================================================================
   Digital Media AI Orchestrator — design system
   ============================================================================

   Direction: "studio, not SaaS".

   This is a marketing production tool — it generates video, images and copy.
   Generic blue-and-white SaaS chrome fights that: it competes with the work
   for attention and makes generated media hard to judge. So:

   - Dark-first. Near-black neutrals give generated media a neutral ground.
     Light mode is a supported alternate, not the default.
   - ONE saturated accent, reserved for generation state and primary actions,
     so "something is being created" is legible at a glance. Everything else
     is neutral. An accent used everywhere signals nothing.
   - Semantic status colours are fixed to pipeline stages and mean the same
     thing in the queue, the calendar and the media grid.
   - Density is compact by default. Operators live in these screens all day.

   These tokens are the durable artifact. Markup can be rebuilt; the scale,
   ramp and semantics should survive a framework change unchanged.
