 * pocket.services — the whole design system in one file.  The palette
 * is the qwabbl brand family (app/static/css/tw/input.css is the
 * upstream source of the values): brand green #8abc5a for fills,
 * #5d9f23 for green text on light, promoted to the text accent on
 * dark.  Inter variable is self-hosted (no third-party requests —
 * the colophon on the page is a factual claim, keep it true).
 *
 * ZERO JavaScript by design: theme follows prefers-color-scheme only
 * (no toggle, so no [data-theme] states exist), and the nginx CSP is
 * default-src 'none' — an inline style attribute or <style> block in
 * the pages would be the first step toward breaking that posture.
