/* ============================================================================
   Amberpane — the platform design system.  Direction: Aperture, v1.0.

   This is the ONE stylesheet every server-rendered page links. It carries the
   tokens, the reset and the component vocabulary, and it is deliberately the
   same vocabulary the marketing site uses (amberpane_website/assets/css) so
   that the signed-in product and the site read as one system.

   These are the PLATFORM's own tokens. They are NOT white-label slots.
   The white-label slots are player.css / player2.css's --primary, --accent,
   --bg …, which export.apply_branding() writes over per brand profile. The
   two files share ten names on purpose — that shared contract is the brand's
   white-label promise — but nothing in here is ever themed by a customer.

   The brand is carried by STRUCTURE, so colour can be taken away without the
   design falling apart:
     · one border weight (1px), 2px radius on controls, 0 on containers
     · two elevation levels — flat, and one modal shadow. No card shadows.
     · flat warm paper. No gradients, no textures, no illustration behind text
     · the aperture notch (12px, 1px, ink, top-right) at most once per view
     · status is an 8px square or a mono caps pill, never an icon, never emoji
     · numbers and machine strings are always mono
   ========================================================================= */
