VIEWPORT =

Surfaces FujiAdmin.config and the responsive viewport hint to the browser by writing into AA’s head. We deliberately avoid ‘namespace.meta_tags`: AA renders that hash inside Arbre as `text_node(meta(…))`, and the inner `meta(…)` already auto-attaches to <head>, so each entry would render twice. Using `namespace.head` (a raw, html_safe string AA inserts once) sidesteps that.

  # Logged-out pages use a separate ERB layout that only renders

  # `fuji-default-palette` so the login screen paints in the configured
  # brand colour. The picker UI itself is hidden for logged-out, so
  # `fuji-palette-picker` isn't needed there.
