/*
 * SAYLURE public landing — saylure.com
 *
 * Self-contained: system fonts, local assets, no CDN, no tracker, no framework.
 * Colours come from the app's own dark theme (packages/design-tokens), and the
 * starfield behind the page is the app's real wallpaper asset, so the site and
 * the product look like the same thing.
 *
 * The one hard layout rule: a real app capture is never squeezed to make a row
 * fit. `--screen-w` is set per breakpoint and every phone image is exactly that
 * wide; when a row can no longer hold three of them, the row wraps.
