/* Shared across every page: account nav dropdown + sign-in modal.

/* ---- Tools nav dropdown (Colour-Control / Root-Frame) ----
   Uses the same [data-auth-toggle] open/close/outside-click/Escape wiring
   in js/site.js as the account dropdown - that binding is generic, so this
   needed no JS changes, only markup + these styles. Independent of the
   .nav-account rendering, so it works the same whether a visitor is signed
   in or not.

   DESIGN RULE: this dropdown and the account (Sign In / logged-in) dropdown
   below share the same rounded-corner convention as .auth-panel (16px on
   the outer menu, 10px on each item) - part of the site-wide "tasteful
   rounded corners, never a sharp box" rule. */
