   plans.css — the Billing / Plans page (/plans), restyled to match the
   marketing home page (home.css). Fully scoped under `.plans-pro` (a body
   class only plans.html sets) and self-contained: it carries its own tokens,
   living background and fx helpers rather than depending on home.css, the
   same way projects.css does. Behaviour (constellation, reveal, spotlight,
   tilt, magnetic, the monthly/yearly toggle) is reused from home.js, which is
   fully null-guarded on pages that lack the hero markup.

   No sidebar here on purpose — Billing is a full-width page under the shared
   base.html navbar.
