/* =========================================================================
   INTERIORS PAGE — page-specific styles only (interiors.css)
   Global rules (reset, colors, fonts, .container, .btn, .card, .grid, .hero,
   .section, .section-head, navbar, footer) live in /style.css.
   Only this page's own layout belongs here. Colors/fonts come only from the
   §6/§7 variables — no new colors; --dusty-denim is the only accent.
   Load + scroll reveals are AOS (data-aos in the HTML); hovers are pure CSS.
   Identical in /pages/en/ and /pages/ar/ — RTL tweaks use html[dir="rtl"].
