/* =============================================================================
   Ofertazas — design tokens and components.

   The palette, the type scale, the spacing rhythm and the motion timings all
   live in `:root` as tokens. Nothing below this block uses a literal colour:
   every value is a token, so a change lands everywhere at once and the dark
   remap is a single block at the bottom of the token section.

   Every pairing here was measured, not eyeballed — the ratios are in the
   comments next to the tokens that carry meaning. The rules that matter:

     - body text sits at 4.5:1 or better on every surface it can land on;
     - borders that carry meaning (inputs, control edges) sit at 3:1 or
       better, which a decorative hairline does not have to;
     - the sale colour is a second, independent hue, never the accent and
       never the success colour, so a discount never reads as a link or as
       "in stock".

   The old token names (--bg, --panel, --panel-2, --line, --control) survive
   as aliases of the new semantic set, so anything not rewritten in this pass
   keeps working and inherits the new palette.
