 * The flow becomes a full-screen app: phone-width column, a sticky

 * primary action fixed to the bottom of the viewport (the mock's
 * action bar). Presentation only — every element id, class and DOM
 * position app.js relies on is unchanged.
 *
 * Two load-bearing details:
 * 1) .card loses its backdrop-filter here. A backdrop-filter on an
 *    ancestor makes that ancestor the containing block for fixed
 *    descendants (the same trap documented above for the immersive
 *    wrap): with the blur on, the "fixed" primary would anchor to
 *    its card instead of the viewport. The cards sit over a
 *    near-white glow, so the blur was barely visible anyway; the
 *    fill steps up to --glass-strong to compensate.
 * 2) The fixed primaries sit at z-index 45 — above the app bar,
 *    below the immersive wrap (60), the camera overlay (80) and
 *    the immersive Done bar (90), so full-screen modes cover them. */

/* The screens' primary actions, pinned to the viewport bottom.
 * The DOM (and therefore app.js behaviour) is untouched: these are
 * the same buttons, lifted out of the flow visually. Disabled
 * buttons already carry pointer-events:none (rule above), so a
 * not-yet-unlocked Continue never blocks the content under it.
 * Intro exception (owner, 2026-11-06): #btn-start is NOT pinned —
 * it stays in the card flow right after the consent checkbox,
 * where the removed "Book an assessment instead" link used to sit
 * (no booking CTA belongs on the Start screen: no test taken yet,
 * and the floating button detached from the card collided with
 * the browser toolbar on the owner's phone). */
