/*
 * Takumi Kin - theme.css
 *
 * Measured from the brand's Figma file (PRE-LAUNCH · Desktop 1921), not from a bought template:
 * there is no vendor sheet under this one, so every class the components emit is defined here.
 *
 * THE FONTS, AND THE TWO THAT ARE NOT HERE
 *
 * The design uses four families. Two are free and ship in assets/fonts/: Inter (the paragraph, the
 * field, the small print) and Josefin Sans (the button). Two are commercial and cannot be bundled:
 *
 *   Helvetica Neue    the heading and the eyebrow. Used where the visitor's system has it (every
 *                     Apple device); elsewhere Inter stands in, which is the closest free face.
 *   Freight Big Pro   the gold italic words. An Adobe Fonts family. Until a kit is added the
 *                     stack falls to Cormorant Garamond, shipped here and scaled to sit at the
 *                     same size. Adding the kit needs use.typekit.net in the site's
 *                     csp_extra_origins, or the policy blocks it without a word.
 *
 * Self-hosted because the site's Content-Security-Policy allows font-src 'self' only.
 *
 * BREAKPOINTS: 991px and 767px, the two theme.json declares. No others.
