   CODEBLOOM — SHARED STYLESHEET
   Cross-app chrome: design tokens, base, buttons, header,
   ecosystem rail, and modals. Workspace styles live in each
   app's own styles.css.

   Source of truth for the suite. Keep app-specific rules OUT
   of this file — chrome/brand/nav belongs here, workspace does
   not. Variable definitions are at the top by design.
