/*
 * Self-hosted Inter, for the standalone HTML under /public.
 * ─────────────────────────────────────────────────────────
 * The Next app does NOT use this file — it gets Inter through next/font (app/layout.tsx).
 * This exists only for the static decks and mockups in /public, which are plain HTML and so
 * sit outside the app's font pipeline entirely.
 *
 * WHY IT EXISTS. Three shipped pages — homepage-alt, the investor deck and master-plan —
 * each carried their own <link> to fonts.googleapis.com. Every visitor to any of them handed
 * their IP address to Google before any consent interaction: the same defect fixed in the app
 * on 29 July 2026 (LG Munchen I, 3 O 17493/20 awarded damages against a site operator for
 * exactly that), still live here because the fix had only ever been applied to the app.
 * Nothing is requested off-origin now.
 *
 * A fourth, labs/run/athlea_run_lab_3d_v4.html, asked for "Inter" without ever loading it —
 * so the Run Lab embedded on /running rendered in whatever the visitor had installed.
 *
 * It also holds the pages to the Inter-only contract: the deck and master-plan were naming a
 * second family for numerals. There is one face now.
 *
 * PROVENANCE. Variable Inter, weights 100–900, in the same seven unicode-range slices Google
 * serves, lifted from the woff2 files next/font had already downloaded for the app build —
 * so the app and the static pages render from byte-identical files.
 *
 * LICENCE. Inter is SIL Open Font License 1.1, © The Inter Project Authors. Self-hosting is
 * permitted; see README.md in this folder.
 *
 * To add a page: <link rel="stylesheet" href="/fonts/inter.css"> and use var(--font-sans).
 * Do not reintroduce a <link> to a font CDN.
