/* ===========================================================================
   DESIGN SYSTEM
   Every value below comes from one of four fixed scales. Nothing in this
   sheet may invent a one-off number: if a value is needed, it is added to a
   scale first. That is what keeps spacing, alignment, and control heights
   consistent instead of drifting per component.

   SPACE     4px base, doubling and half-steps:  4 8 12 16 24 32 48
   TYPE      11 12 13 14 18 24 px, each with a fixed role (see --fs-*)
   CONTROL   fixed heights 22 / 28 / 34 / 40 shared by every button, input,
             select, chip and badge, so any row of controls aligns by default
   RADIUS    6 / 8 / 14 / pill

   COLOUR    a 4-step surface ladder (bg < surface < raised < sunken) plus
             semantic accents that each carry a -soft fill and a -line border,
             so a badge, a bar and a border always agree on tone.
