/* Sheetsnap's public pages.
 *
 * The palette is the app's own (docs/02-APP-SHEETSNAP.md §6) so that somebody
 * who taps "Privacy" inside the app and lands here does not feel handed off to
 * a stranger's website. Same green, same mint, same paper, same ink.
 *
 * No fonts, no scripts, no analytics, no cookies, no external requests of any
 * kind. A privacy policy that loads a tracker is a joke that writes itself, and
 * these pages are also the answer to "does this site set cookies?" — it does
 * not, which is why there is no cookie banner and no cookie section.
