/* public-form.css — Pass 3c primitives for registration.html (+ future
 * summer-camp.html in 3d). Loaded ONLY by public-form pages, NEVER by the
 * dashboard. Stays cohesive under the ~700-line tripwire from
 * kore-architecture-folder-structure.md §5.
 *
 * Re-implements the legacy registration/registration.css visual signature in
 * Kore BEM classes referencing base.css :root tokens. No #rtp-dashboard-
 * wrapper, no !important outside the sanctioned exceptions, no inline styles.
 *
 * Sections:
 *   1. Page chrome + decorative blobs
 *   2. Gradient header banner + STEAM chips
 *   3. Countdown (used when REGISTRATION_OPENS_AT is in the future)
 *   4. Stepper (4-step progress nav)
 *   5. Form card + steps + inputs + grid + actions
 *   6. Consent checkboxes + honeypot + captcha
 *   7. Result views (success / waitlist / duplicate / error)
