/* ============================================================================
   User menu
   The header auth control, in the style first used on the Frontier PDM app
   (static/growthguru/pdm/index.html).

   Exactly one control is visible at a time:
     signed out — a single primary "Sign In" button. No ghost avatar, no
                  "Guest" label.
     signed in  — a pill trigger (avatar + name + caret) that opens a dropdown
                  holding Account settings, any page-specific items, and
                  Sign out.

   Rendered by static/js/auth/user-menu.js.

/* Every colour resolves through a chain, so this drops into either variable
   vocabulary in the codebase without per-site overrides: the app themes
   (--text-color / --border-color / --accent-color), GrowthCanvas
   (--text / --line / --accent), then a literal.

   --accent is checked BEFORE --accent-color: only a site that means it declares
   --accent, whereas --accent-color always has a generic value from theme-base,
   so preferring it would paint GrowthCanvas's orange header blue.

   A site whose brand colour lives somewhere else entirely can point the menu at
   it by overriding --um-accent on .um — see essentialgovernance-theme.css. */
