/* ============================================================
   Project Builder — shell + shared primitives
   ------------------------------------------------------------
   Loaded on EVERY /projects/ page, right after pb-tokens.css.

   Holds the two things every page needs — the indigo hero band
   and the button/notice primitives — plus the workspace's
   two-column layout and its contextual left rail.

   `.pb-btn` lives here rather than in pb-workspace.css because
   the hub, the chooser and the wizard all use it and none of
   them load the workspace stylesheet.

   The workspace's left rail is a column inside the page's
   content block — it is NOT an override of base_app's sidebar
   block. That block is the platform's global nav, and .pb-scope
   (where the --pb-* tokens are declared) is a sibling of it, so
   the tokens could not reach an overridden sidebar anyway.
   ============================================================ */

/* Alpine's x-cloak is inert without this rule, and there is no global one in

   and only collapses when Alpine boots. */
