/* ════════════════════════════════════════════════════════════════
   Fourka — showcase page (نمونه‌کارها).

   Loaded only on that page, after front.css, and built out of the
   landing's own pieces (.hero.page-hero, .eyebrow, .lead, .section,
   .section-mist, .btn) so it matches the site by construction.

   Mobile first — roughly 90% of visitors are on a phone. Every
   project is the same record in the same order; the only thing that
   varies is the frame around the screenshot, which follows the kind
   of project (phone for an app, browser for a website).

   RTL: inline-start is the right edge. No letter-spacing on Persian.
