/* The shared product page — /products/<slug> and the admin's preview of it.
 *
 * One column on a phone, in the page's source order (photos, title, price,
 * form, description, reviews). From 900px the photos and the buying column sit
 * side by side, and everything from the description down returns to one
 * column at reading width. Every value is a token from tokens.css
 * (css-tokens.test.ts holds that line).
 *
 * Phone first. At 375px nothing here may be wider than the viewport: images
 * are `max-width: 100%`, long words break (`overflow-wrap: anywhere`), and
 * the gallery's thumbnails are a grid, never a row that scrolls the page.
