/*
 * N43Mont — luxury.css
 * ─────────────────────────────────────────────────────────────────────────
 * Presentation-layer polish effects, deliberately kept in their OWN file,
 * separate from reveal.css and app.css. These are purely additive: entry
 * curtain, scroll progress bar, magnetic tilt support, ambient cursor glow.
 *
 * None of these selectors overlap with anything in reveal.css or the
 * Tailwind-compiled app.css — verified by grep before shipping. Removing
 * this file entirely (unhooking one line in functions.php) instantly and
 * completely removes every effect below with zero impact on the rest of
 * the site, by design.
