     to frame position. Scroll is captured (locked) while this section
     fills the viewport, and each gesture snaps to the next/previous
     room via an auto-animated tween (see app.js).
     100vh kept as a fallback; 100svh ("small" viewport height — the
     height once a mobile browser's address bar is fully shown) is the
     REAL fix for mobile: plain 100vh is taller than the actually-visible
     viewport while the toolbar is showing, so this section's box never
     quite matched the on-screen viewport on phones. app.js locks scroll
     capture only once its IntersectionObserver sees the section at
     ~full ratio — with the old 100vh/actual-viewport mismatch that ratio
     could never reach threshold on mobile, so the lock never engaged and
     the whole gesture-driven tour silently never started (no error, just
     no animation — scroll just ran straight through it). svh is a fixed
     value that doesn't change as the toolbar shows/hides mid-interaction
     (unlike dvh), which matters here since the lock state must stay
     stable through a gesture, not recompute under it. */

/* ============================================================
   AUREA BACKDROPS — animated, photography-free, LIGHT palette
   From "Materials" onward the villa's own photos started repeating shots
   already seen in the tour above, so those three sections (.feature__bg on
   Materials + the closing terrace band, .viewing__bg on Contact) carry a
   living abstract composition instead: a warm paper/cream field (matching
   the Specs section's already-light palette, not the dark tour) with two
   very soft, low-opacity colour washes drifting on independent, non-round
   cycles (26s/32s, 34s/40s, 30s/24s) so the motion never lines up into a
   visible loop, over a fine static grain so a plain gradient never reads
   as flat. Pure CSS — no extra image weight. Deliberately understated: the
   colour tints sit at 7–16% opacity, a hint of hue rather than a block of
   colour, so the overall impression stays white/cream and elegant. Each
   section keeps its own faint palette so Materials, the terrace line and
   Contact still feel distinct from one another. This layers underneath the
   existing bgDrift zoom + the scroll parallax (--py) on the very same
   element, so all three motions compose together.
