   party-beach-card-postcard-paradise — "Postcard from Paradise" (Beach Party · Card)
   Printed-stationery postcard · seafoam paper + sand + navy ink + coral + sun.

   Layout contract:
     · The single-viewport shell is gated on body.shell-on, added by main.js
       only when 2+ panels survive platform processing. Without it (no JS, or
       a single panel left), the page is a normal stacked, scrolling document.
     · With .shell-on, .app-shell locks to 100dvh and only the ACTIVE panel
       scrolls internally.
