/* ==========================================================================
   ORELKA — styles.css (consolidated, light refonte)
   - Merges main.css + noscript bits, keeps existing class names where possible
   - Cleans vendor prefixes, adds CSS variables, responsive rules, and utilities
   - Palette kept from legacy: bg #242629, accent #34a58e, text #a0a0a1, border #36383c
   - You can safely remove main.css + noscript.css after switching to this file
