/* ── The securitai.io header, for the pages the site links out to ────────────
 *
 * signup.html and set-password.html are reached straight from the marketing
 * site and from our emails, and each had grown its own idea of a header:
 * signup put the logo on a dark navy band, set-password had no header at all
 * and a text wordmark inside the card. Neither looked like the site the visitor
 * had just left.
 *
 * One file rather than a copy per page, because "the same header" is only true
 * for as long as nobody edits one of them.
 *
 * Colours and sizes are literals, not var(--...). Each page carries its own
 * token block with its own values for the same names — signup's --border is
 * #E2E8F0, the portal's is #D8E0EC — so a shared component that read them would
 * render differently on each page, which is the thing it exists to prevent.
 * These are the site's own values:
 *   white bar, #E3E9F2 hairline, #1C3C6E link navy, 1140px content, 62px logo.
