   Proficiency Coffee — Executive Dashboard
   Ported from the Apps Script exec_v4 project (Executive.zip)
   so the PHP rebuild reads as the same product, not a redesign.
   Tokens, class names and shell layout are copied as-is; the
   parts that depended on Apps Script (Chart.js, client-side
   SPA routing, Google auth) are simplified for a server-
   rendered multi-page app instead. See CLAUDE.md.
