/* ---------------------------------------------------------------------------
   The engineering ledger.

   This plan started life as a spreadsheet on a Windows desktop, so the page is
   built as a ruled ledger rather than a dashboard: paper ground, ruled panels,
   no floating cards, no drop shadows, no rounded corners. Calibri is the house
   face and stays for words; every figure is set in Consolas, the font that
   ships beside it, so hours and ticket keys align in columns the way they do in
   the sheet.

   Colour discipline: Safra gold, green and charcoal for the document; the chart
   hues are the validated pair only (see charts.js). Gold never carries small
   text — it fails contrast on this ground — so there is a separate darker gold
   reserved for type.
