/* Yomita — product pages (/products/*)
 *
 * Loaded after /styles.css and builds on its tokens and components: .topbar,
 * .hero, .head, .ph, .btn, .eyebrow, .chip, .principles. Nothing here redefines
 * a token. A change to the palette belongs in styles.css, not here.
 *
 * In a file of its own rather than in <style> for the same reason as wave.js:
 * the Content-Security-Policy is `style-src 'self'` with no 'unsafe-inline'
 * (client/nginx.conf). Inline `style=""` attributes are blocked too, so every
 * one-off goes into a class here.
 *
 * The three `.ph` shapes below carry real art and so are cut to what was
 * actually shot: screenshots at roughly the iPhone's 1170×2470 (the captured 2532
 * less the debug HUD along the bottom, which is a dev-build overlay and not
 * part of the app), photographs at 16:9 wide and 4:5 tall.
 * Change a crop and change the matching aspect-ratio, or `object-fit: cover`
 * will silently trim the subject out of the frame.
