/* ===== rc_header_html (HTML form, scoped) =====
   Loaded eagerly from anvil.yaml native_deps.head_html. Anvil strips a template's <style> text, so
   these rules cannot live in form_template.html.

   .rc-header is the form root and is already private: it is declared nowhere else in the app, so it
   is kept as the root class rather than a private one being added beside a shared one. The root rule
   stays a BARE class so it outranks the scoped descendant rules; every other rule is scoped
   :where(.rc-header), which adds no specificity and so cannot change which rule wins.

   No second class is needed anywhere in this file.

   DESIGNER LIMIT, as recorded in rc_lateness_html.css: this asset styles the canvas, but the --px-*
   colour tokens are injected at runtime by the dependency's ensure_theme_injected(), so the canvas
   shows this layout with unresolved colours. Runtime is unaffected. */
