/* --- Hero: CRT-style templating-syntax flicker cameo ---------------------
   Automatically alternates the rendered headline with the real template
   tags that generate it, using a proper old-TV signal-glitch look:
   blackout frames, chromatic-aberration text-shadow, a rolling scan bar,
   and a static-noise texture — driven from JS (see index.html) which sets
   opacity/transform/filter/text-shadow per frame; the CSS here just
   supplies the base look and the rolling-bar/noise overlay. Shown as
   real, multi-line Birkly template syntax (from/get/endget), monospace,
   no dark box — sits directly over the hero, transparent background.
   Braces are HTML-entity-escaped so the live templating engine never
   tries to resolve them as real fields. The rendered <h1> stays in the
   DOM at all times (only its inline styles change), so assistive tech
   always has the real heading; the syntax layer is aria-hidden and,
   under reduced motion, never shown. */

 * Deliberately CSS-only, driven by hidden radio inputs. This page has had a
 * long run of JavaScript-timing bugs, and a section whose entire job is to
 * switch panels does not need a script to do it. It also means the section
 * works before any JS loads, and keyboard/screen-reader behaviour comes free
 * from the radio group.
