/* portal.css — the landing portal at `/` (q-portal-landing-page).
 *
 * Deliberately standalone: the MMORPG page at /world/ keeps tg-styles.css + scrollytelling.css,
 * and nothing here is loaded there. The portal is plain HTML/CSS/vanilla JS — no React, no build
 * step, no new runtime dependency (AD-261).
 *
 * Palette follows docs/art/art-direction-bible.md §3 and §15: deep twilight blues and violet,
 * warm lantern gold as the single accent, Cloud-iridescence reserved for the Cloud itself.
 * Contrast: every text/background pair below is at or above WCAG AA for its size — the section
 * art sits behind a scrim tuned so body text on it stays ≥ 4.5:1.
 *
 * 2026-09-18 visual pass (owner: "clean but bland"): key art behind each section as a lazily
 * loaded <img> under a scrim, glassy panels, gold/violet glows, and a slim top bar that links the
 * two destinations from anywhere on the page.
