/* Spredin — site styles.
 *
 * PALETTE: the app's own "Paper" theme, copied value-for-value out of
 * `src/theme.ts` in the app repo — not approximated, not re-picked. Paper is
 * the identity the brand is built on: it is what the app icon is drawn in
 * (App Store, Finder, the Dock), and it is what this site has always used.
 * Landing on the page and then opening the app should feel like one thing, so
 * the ivory, the terracotta and the slate teal here are the same hexes the
 * grid paints with.
 *
 * The accents below are Paper's PRIMARY accent plus three series of Paper's
 * own chart palette:
 *     #c96442 terracotta   #4f7d8c slate teal
 *     #b9972f gold         #6f8f7b muted green
 * They give the page some life without a single invented colour.
 *
 * CONTRAST WAS MEASURED, NOT EYEBALLED, and the numbers decided the usage:
 *     --ink      #29251d  14.5:1   body text
 *     --ink-2    #6d6555   5.5:1   secondary text, AA at any size
 *     --ink-3    #7d7460   4.4:1   DECORATIVE LABELS ONLY — see below
 *     --accent-ink #a54c2f 5.4:1   link and accent text
 *     --accent   #c96442   3.7:1   fills, rules, icons — never small text
 *     --accent-2 #4f7d8c   4.3:1   ditto, plus large display numerals
 *     --green    #6f8f7b   3.4:1   ditto
 * The vivid three clear the 3:1 bar for large text (>=24px) but not the 4.5:1
 * bar for small, so they are used for the big stat numerals, rules and icons —
 * and nowhere else.
 *
 * `--ink-3` is the one to be careful with. It was briefly Paper's own
 * `--text-faint` (#a39a86), which measures 2.65:1 here — fine inside an app
 * where it labels a grid header next to the data it describes, and much too
 * light for a web page read at arm's length. It is now Paper's
 * `--grid-header-text`. At 4.4:1 it is still 0.1 short of AA for small text, so
 * ANYTHING THAT IS A SENTENCE USES `--ink-2`; `--ink-3` is reserved for
 * micro-labels, captions' chrome and the mock grid's own header row.
 *
 * TYPE: Paper is set in Charter — a book serif that ships with macOS. Display
 * type here uses the same stack so headlines carry the app's voice; body text
 * stays in the system sans, which reads better at 15-17px on the Windows
 * machines a lot of this audience is still browsing from.
 *
 * NO EXTERNAL REQUESTS ANYWHERE. No web fonts, no analytics, no CDN, no
 * JavaScript at all. A product whose pitch is "your data stays on your Mac"
 * cannot have a landing page that phones three companies to render a headline.
 * This is checkable: open any page and look at the network panel.
