 * WHY THIS LOOKS THE WAY IT DOES
 * ---------------------------------------------------------------------------
 * Someone reaches this page seconds after a call they did not expect, on a
 * phone, already suspecting a scam. Every rule below serves one of three ends:
 * they can read it, they can believe it, and they can leave to check it.
 *
 * It borrows the NHS.UK DESIGN LANGUAGE - the calm blue bar, the reading
 * measure, the care-card components - because that grammar is what people
 * recognise as an official health page. It deliberately does NOT borrow the
 * NHS IDENTITY: no NHS logo, no NHS wordmark, no NHS lozenge, and a blue one
 * shade off theirs. Those marks are protected, and a page that pretends to be
 * NHS is exactly the thing patients are told to distrust.
 *
 * To adopt the exact NHS blue instead, change --cc-brand and --cc-link in the
 * one block below. Nothing else in this file hard-codes a brand colour. Read
 * DESIGN_NOTES.md before you do - it is a legal decision, not a visual one.
 *
 * ---------------------------------------------------------------------------
 * COLOUR
 * ---------------------------------------------------------------------------
 * Every pairing used here is verified by scripts/check-contrast.mjs against
 * WCAG 2.2 AA. If you change a value, run `node scripts/check-contrast.mjs`
 * and add the new pairing to that file. Two values already moved once because
 * the check failed them: the border was #A2B0B9 (2.22:1, invisible in
 * sunlight) and is now #6F8089.
 *
 * SINGLE THEME, ON PURPOSE. This site commits to a light appearance, as
 * NHS.UK does. `color-scheme: light` stops browsers auto-darkening form
 * controls into something that no longer matches the page, and every surface
 * paints its own background so nothing is ever inherited from the host. What
 * IS supported properly is Windows High Contrast (forced-colors) at the foot
 * of this file, which is what the users who need it actually use.

   * NO WEBFONT, ON PURPOSE - two reasons, both of which beat a nicer face.
   *
   * 1. PRIVACY. Fonts served from Google send every visitor's IP address to
   *    Google. A Munich court held that unlawful under GDPR in January 2022,
   *    and on a health-adjacent page it would have to be declared in the
   *    privacy notice. Removing it deletes a whole third-party disclosure.
   *
   * 2. AUTHENTICITY. NHS.UK sets "Frutiger W01", Arial. Frutiger is licensed
   *    to the NHS alone, so virtually every real NHS.UK visitor is already
   *    reading Arial. Arial IS the NHS look on the devices that matter.
   *
   * It is also the fastest possible option on a poor mobile connection,
   * which is where this page gets read.
   *
   * The two roles below are separated by weight, size, tracking and numeral
   * style rather than by family. To self-host Source Sans 3 and Public Sans
   * instead - both SIL OFL, so redistributable - see README.md.
