   The legacy component layer below (~2000 lines) is written against these
   token names, which is why the blue-* names survive: they are now WARM
   values, so every legacy component re-skins from this block alone rather
   than needing 2000 lines of find-and-replace.
   Layout is NOT handled here — see the KORVA v3 FULL-VIEWPORT LAYER at the
   end of this file, which deliberately loads last so it wins on source order.

   KORVA v3 — FULL-VIEWPORT LAYER
   ------------------------------------------------------------------------
   Loads LAST on purpose. The legacy sheet above centres everything inside a
   1140px column, which letterboxes the product on any screen wider than a
   laptop and makes it read as a document rather than a service. Rather than
   surgically unpicking ~2000 lines, this layer overrides the layout
   primitives at the same specificity and wins on source order.

   The rule this whole layer enforces: STRUCTURE spans the viewport, TEXT
   does not. A grid row runs edge to edge; a paragraph inside it is capped at
   a readable measure. Those are different jobs, and the old sheet conflated
   them by capping the row.

   KORVA NAV LAYER — persistent top nav, breadcrumbs, mobile bottom bar
   ----------------------------------------------------------------------------
   Appended LAST on purpose. Two rules of engagement in this file:

   1. Media queries add NO specificity. A plain rule that appears later in the
      file beats a rule inside an earlier @media block — that is exactly how the
      old mobile menu ended up permanently open. So: every plain rule in this
      layer comes first, and EVERY @media block comes after all of them, at the
      very bottom of the file. Nothing may be appended after them.
   2. Colours come from the existing tokens (--accent, --ink*, --surface, --line,
      --sec-*). No literal hexes, so a palette swap reskins this for free.
