/* ---------- self-hosted Shabnam (SIL OFL) ----------
   served from this VPS, never from a CDN: Google Fonts and jsDelivr are slow or
   unreachable for many visitors inside Iran, and a font that fails to load takes
   the page's whole typography with it.
   Shabnam ships 300/400/500/700 — nothing heavier. Asking for 800 or 900 only
   triggers synthetic bold, which smears Persian letterforms instead of thickening
   them, so every heading here uses 700. */

/* ============================================================
   ONE breakpoint for the whole stacked layout.

   Everything that makes the page multi-column, and everything that makes
   sections overlap, switches off together at 900px. Splitting these across
   860 and 900 left a 40px band where the form still climbed into the hero
   while the rest had already stacked.

   The overlaps are a desktop device: the card is 1080px inside a full-width
   hero, so the photo shows around it and the overlap reads as depth. Stacked,
   the card spans the full width — there is nothing beside it, so an overlap
   stops looking like layering and just covers the section above. Each section
   becomes its own block with real space between them.

     Full width still: nothing is inset from the left or right edge. The corners
     round against the page background, and a thin gap between sections lets that
     rounding read — without the gap the corners of two touching sections would
     meet and look like a rendering fault rather than a decision.
