/* RxHealing bottle: scroll-driven 3D prescription bottle mounted in the
   homepage device slot. Page styling (including .device-section,
   .device-stage, .device-placeholder and .device-ground) is owned by the
   page's embedded stylesheet. This file adds the stage that holds the WebGL
   canvas, and the program cards that fade in under it.

   States, set by js/hero.js on #bottle-stage:
   - no data-mode (JS off)      -> the placeholder card shows
   - data-mode="webgl"          -> canvas is live; the placeholder stays
                                   visible until the first frame is drawn
   - data-mode="fallback"       -> placeholder shows (WebGL, three.js or the
                                   label art failed)
   - data-state="idle"          -> waiting for the section to come near view
   - data-state="loading"       -> three.js and the label art loading
   - data-state="ready"         -> first frame drawn, canvas fades in,
                                   placeholder fades out
   and on the enclosing .device-section:
   - data-peel="on"             -> peel-to-cards mode is running: the cards
                                   start hidden and JS fades them in
                                   (without it, the cards render in place:
                                   no JS, reduced motion, fallback)
   - is-cards-live              -> the cards have started to appear

   The stage always has the bottle's aspect and centers the placeholder card
   inside it, so the placeholder-to-canvas swap causes no layout shift. */

/* Program cards (#cards, three .peel-card links in the device section), in

   backdrop-filter, border-radius, padding; the Proven Results cards have no
   shadow and no hover state), the grid gap from .result-cards, the eyebrow
   from .eyebrow (the "PROVEN RESULTS" line), the body color from
   .result-stat .stat-label. The markup is unchanged from the earlier
   PNG-style cards: the band span now carries the eyebrow, whose text comes
   from CSS (the span is aria-hidden, so a screen reader still reads each
   program's name once, from the headline), and the lockup is not shown. A
   div rather than a nav: the page stylesheet styles bare nav and nav a for
