/* cursedalchemy.com — hand-written landing styles. No framework, no external
 * fonts (system stack), no external requests.
 *
 * The look (2026-07-31 redesign, owner prompt fix-saas-home-page part-2):
 * "dark-mode aurora tech" — a deep #0b0f19 canvas backlit by blurred aurora
 * glows, glassmorphic cards with 1px translucent edges, and a violet→cyan
 * accent gradient. Emerald stays as the product's "verified / live" semantic
 * color. The page is deliberately dark in BOTH color schemes.
 *
 * Every decorative layer has a pure-CSS base; generated art (site/assets/
 * aurora-*.webp, iso-modules.png) enriches it when present — see DECOR_ASSETS
 * in build.ts. Scroll-reveal styles apply ONLY under html.js, so a JS-disabled
 * visitor (and any crawler) sees the complete page with nothing hidden. */
