/* ============================================================================
   INCAS Layout CSS — Component Library
   Extracted source-of-truth for all INCAS custom components.

   ARCHITECTURE:
     Layer 1 (legacy, read-only): style.15375.css, des.15375.css, wblue.css
     Layer 2 (INCAS custom):
       incas.css        → CSS variables + legacy slider/component styles
       incas-layout.css → THIS FILE — hero, cards, sections, nav overrides
       products.css     → Products & listing pages
       doulton.css      → Doulton brand pages

   DO NOT add unrelated styles here.
   Bump CSS_VERSION in ci4_app/app/Config/Constants.php after any edit.
