/*
  register.css - styles for the early-access form on register.html (task S96-T11).
  Why: the shared styles.css has no form controls; keeping them here leaves styles.css (563 lines)
  under the 600-line limit and loads form styles only on the page that needs them.
  Connects to: register.html (classes .reg, .reg-*, .field*, .check, .hp), register.js (toggles
  [hidden], [aria-invalid], .is-error, .is-busy), and the brand tokens defined in styles.css
  (--surface, --ink, --stone, --border, --hanko, --ok, fonts). Reduced motion: the global
  prefers-reduced-motion rule in styles.css already turns off every transition used here.
  Input: prefers-color-scheme through the tokens. Output: form styling, 360 px and up.
