/* Easel — easel.art
 *
 * The palette, radii and type come from ios/PhotoStyle/Views/Design.swift, so
 * the site and the app are the same warm parchment by day and the same warm
 * charcoal at night.
 *
 * One value is this site's own: --coral-strong, a darker step of the action
 * colour, because the app's own fill measures 3.0:1 against a white label and
 * that is thin on a desktop page. Everything else is the app's, and each token
 * below names which of Design.swift's it is where that is not obvious.
 *
 * Design.swift's rules travel with its values. The one that matters here is
 * the note at Design.swift:93 — control boundaries use `outline`, never
 * `outlineVariant`, which is decorative only and measures 1.62:1.

/* --coral is 2.86:1 on parchment, under the 3:1 WCAG 1.4.11 wants for a
