/* ============================================================================
 * CPWE AI — UI REFRESH LAYER (R24 P4.6 facelift)
 *
 * Purpose: tighten typography, sharpen edges, modernise focus rings
 * and button polish — without rewriting any existing stylesheet. This
 * file loads LAST in the cascade, so its rules override the older
 * design-system + guardian-style sheets where appropriate.
 *
 * Brand colors are PRESERVED (#0FD5C5 teal + #9B4DCA purple); the
 * refresh is about contrast, hierarchy, and tactile feedback.
 * ============================================================================ */
