/* ============================================================================
   The way in — sign in, the emailed code, request an account, request sent.

   FOUR SCREENS, ONE PAGE, NO APP CHROME. These are their own page: no panel,
   no breadcrumb, no bottom bar. A parent meets them before they have an
   account, so the shell would be furniture for a room they cannot enter yet.

   Only the CARD GRAMMAR changed from the pre-redesign screens, and in two
   ways: 18px corners and the shell shadow instead of a hairline border, and
   50px controls instead of 44. Everything else is the same screen.

   ⚠️ Colours come from tokens, including the warm gradient and the two soft
   discs behind the card: --hero-warm, --surface-warm and --callout-warm are
   the canvas's #FFFBEF / #FAF9F5 / #FFF7DB, already in tokens.css. No hex
   entered the system for this page.

   ⚠️ 50px controls are ABOVE the 44px touch minimum (DESIGN.md § 9), not a
   restatement of it. This is a phone-first screen for an audience that is
   mostly on phones, often one-handed, often in a hurry at a school gate.
