/* ═══════════════════════════════════════════════════════════════════════
   Photo Studio — standalone AI image editor (/edit).
   WB-035 (وحش بلال 2026-05-06): full visual rewrite per Bilal "بعدهن
   شكلهن كلش مو حلو مو بروفشنل غيرها كلها بتصميم احلى وارتب بروفشنل".

   DESIGN PHILOSOPHY (strict):
     • Less is more — remove decoration, keep structure
     • Discipline — 3 surface colors, 2 text levels, 1 accent
     • Borders > shadows for separation
     • Spacing > glow for hierarchy
     • Flat panels (NO glass-morphism, NO blur)
     • NO gradients except: primary CTA, brand badge
     • Active = solid accent bg, NOT gradient + shadow + glow

   References: Figma left panel, Linear, Adobe Firefly Web.
   Every .ps-* selector preserved so static/js/photo_studio.js works.

   The previous "smallest" breakpoint was @max-width:980px which still
   assumes a tablet-sized viewport. On phones (~360-480px) the page felt
   oversized — chips overflowed, header padding was huge, canvas dominated
   the screen. This block tightens everything for narrow viewports.
   Why "why" comment: Bilal's photo_studio was designed desktop-first
   2026-04-25; the 980px floor was added without phone testing. Zain
   confirmed 'image edit too big for mobile' on phone PWA 2026-05-10.
