/* ==========================================================================
   المطرودي للمظلات — Almatroudi for Shades
   2026 — refined editorial system. Near-white canvas, generous whitespace,
   confident quiet typography, a single brand-red accent, charcoal reserved for
   a few deliberate moments (hero, services list, closing, footer).
   Type: IBM Plex Sans Arabic throughout; IBM Plex Mono only for Latin numerals.
   Plain CSS, RTL-first, no build.
