/* ==========================================================================
   Story Banner — 1080×1920 Instagram Story generator
   --------------------------------------------------------------------------
   Only the modal / preview chrome lives here (shared by BOTH generators):
     • property pages  → assets/js/property-story-banner.js
     • site stories    → assets/js/story-banner.js
   The banner itself is always drawn on a <canvas> so the output is a true,
   pixel-exact 1080×1920 PNG with correct Persian shaping (no html2canvas
   RTL bugs, no external dependencies).
   Loaded on every landing page (see views/layouts/landing.php).
