/* Iron Forge — front desk (public marketing).
 *
 * Sign-up is NOT here: the CTAs link to the member app's own /register, so there is one sign-up form
 * to style, one to keep in step with auth changes, and one that offers SSO.
 * (fix_front_desk_signup_redirects_to_the_app)
 *
 * Single, deliberate look: the Iron Forge "forge" identity (warm surfaces + ember accent), the same
 * token names the app uses so it feels like one product (docs/branding-and-styling.md). Every colour
 * literal lives ONLY in a --custom-property declaration below; everything else uses var(...) — that is
 * what keeps the colour-drift ratchet (scripts/check-colour-drift.sh) green.
 *
 * Type: three weights only — 400 / 600 / 700 (500 and 800 are banned). Barlow for body, Barlow Semi
 * Condensed for display/eyebrows. Self-hosted (assets/fonts).

     The front desk had NO environment marking on any plane, so test.iron-forge.app was
     indistinguishable from the live marketing site and always had been. The ribbon is now
     single-sourced across all four front ends (frontend/shared/js/staging-ribbon.js), and these are
     the three tokens it needs — the front desk defined none of them, having its own ember palette
     rather than the consoles' status scale.

     --warning and --on-warning are the style guide's FIXED values (docs/branding-and-styling.md),
     not a re-theme: the amber warning fill and its deep ink are the same on every surface by design,
     which is the whole point of a warning colour. ⚠ Do NOT swap them for --primary here — an ember
     band would read as the Iron Forge brand accent rather than as "this is not production".
