/* parentproof.com — the marketing site.
 *
 * SAME TOKENS AS THE APP, ON PURPOSE. --glow, --ink, --cloud, --coral, --mint
 * and --sky are lifted verbatim from platform/public/app.css. A visitor who
 * reads this site and then signs in at platform.parentproof.com must not feel
 * they have arrived at a different company. If a token changes there, change it
 * here in the same commit.
 *
 * SYSTEM FONTS, no webfont, no CDN, no analytics script, nothing third-party.
 * The app makes an argument about staying small and touching nothing; a
 * marketing site that opens with 300KB of font bytes and a tracker contradicts
 * it on the first page a parent ever sees. This stylesheet is the whole design.
 *
 * NO INLINE STYLE ANYWHERE in the pages this serves — same discipline as the
 * app, so the site can move behind the app's `style-src 'self'` CSP without a
 * rewrite.

 * --bg, a combination the app never uses. On #EDEAE1 the app's values measure
 *   --glowink #9C6700  4.01:1   --mint #0E7C52  4.34:1   --sky #2C6BD1  4.23:1
 * — all under the 4.5:1 normal-text floor. The values below measure 4.88, 5.22
 * and 4.99. axe-core reported every one of these as a serious violation before
 * the change and none after; see tools/contrast-check.py to re-derive them.
 *
 * Light is the default for a marketing page — a parent arrives from a search
 * result in daylight — and dark follows the OS. Same two-palette structure the
 * app uses, so a screenshot of one drops into the other. */
