/* Rootio — the public site.
 *
 * Every colour here is transcribed from `../Rootly app/src/theme/colors.ts`,
 * which is itself transcribed from the design handoff. If a value looks wrong,
 * that file is the arbiter, not this one.
 *
 * There is no JavaScript on any of the *public* pages, deliberately: helmet's
 * default CSP allows inline styles but not inline scripts, so a page that
 * needed script would need a CSP exception, and none of them does. The theme
 * follows the OS.
 *
 * `/admin` is the one exception, and it needed no exception to be made. It
 * loads its script from `admin-assets/` — external and same-origin, which
 * `script-src 'self'` already allows — and binds every handler with
 * addEventListener, because `script-src-attr 'none'` forbids an inline
 * `onclick`. The CSP is therefore untouched, which matters: loosening it here
 * would loosen it for the two pages a store reviewer reads. `admin.css`
 * extends this file and defines no colour of its own.
