/* ═══ RADATTEST — SYSTEM v1 (2026-08 redesign) ═══════════════════════════════════════
   The layout DNA that replaced the long-form editorial pages: every feature earns one
   real graphic + one short line, and the product is the page. Shared by the merged
   landing (index.html) and the audience pages. The old site.css keeps serving any page
   not yet migrated; delete it when the last one moves over.

   Kept deliberately from the old system: the palette, Instrument Serif / Instrument
   Sans / Azeret Mono (display / body / UI-voice), and the boxed chrome idiom the film
   page established (pale fill, ink border, accent edge for the current page).         */

   --zoom-want is the lift this frame ASKS for. --zoom and --zoom-x are what it GETS,

   can show, plus a sideways nudge for a frame that sits off-centre and would otherwise
   grow off one edge. body has overflow-x:hidden, so that excess is not something a reader
   can scroll to — it is silently cut off, and a hover meant to reveal the priors rail was
