/* ============================================================================
   IOU Component Styles (Day 3-4 beachhead)
   ----------------------------------------------------------------------------
   Isolated from style.css so the primitives added during the beachhead are
   easy to find, roll back, or extend. When the two-week beachhead proves
   out and propagates, this file's contents merge into style.css.

   Rule: no hardcoded spacing or type. Everything reads from --sp-* / --tp-*
         / --st-* tokens defined in tokens.css.
