/* ============================================================================
   QUATRON · PRODUCT SCREENS
   The visual layer for product modules (Gold, Gold Operations and anything that
   uses the same markup helpers).

   WHY THIS FILE DID NOT EXIST
   ---------------------------------------------------------------------------
   The product modules have always emitted `qtr-card`, `qtr-kpis`, `qtr-table`
   and friends, and NO stylesheet in the deployment defined any of them —
   verified by grepping every .css under deployment/: zero matches for
   `qtr-card`. So the markup was correct and complete while the browser had
   nothing to draw, which is why the Gold centre rendered as a flat list of
   unstyled text with `background: transparent; padding: 0; border-radius: 0`
   on its panel.

   It is a separate file rather than an addition to platform-shell.css because
   the shell is the chrome around a product and this is the inside of one; they
   are owned by different phases and change for different reasons.

   TOKENS, WITH FALLBACKS
   ---------------------------------------------------------------------------
   Every colour and radius reads a design token first and falls back to a
   literal. If design-tokens.css is loaded the product inherits the brand; if it
   is ever loaded late, or a token is renamed, the screen degrades to something
   readable instead of to invisible text on an invisible card. The fallbacks are
   not the design — they are the floor under it.

   RTL is not special-cased: the layout is flow-relative throughout
   (margin-inline, padding-inline, border-inline-start), so Arabic and English
   use the same rules rather than a mirrored copy that drifts.
