/* ============================================================
   UpgradeAirKit.com — cfm-table.html "CFM Table for Building Permit"
   The room-by-room sizing tool + the sheet a permit reviewer reads.

   LOAD ORDER: this file must be linked LAST, after design-system.css,
   shop.css, dev-enhancements.css and nav.css. Everything here is scoped
   under a .cfm-* ancestor on purpose — shared furniture (.btn, .card,
   .field, .page-band, .site-header, .site-footer) is extended, never
   redefined, so no other page can be disturbed by this stylesheet.

   Tokens only — see design-system.css. The two flow-column tints and the
   panel shadows are alpha derivations of existing tokens (--navy #0C2A4D,
   --gold, --green). No new brand colour is introduced; the only bare hex
   values are the sanctioned on-navy tints (#EAF1FB / #6BE08C / #C6D6EA, as
   used by .page-band in shop.css) and neutral greys inside @media print.
   Breakpoints: 1100px · 880px · 560px. Nothing else.

   This file also carries the site's FIRST @media print block. The printed
   page IS the permit document — treat that section as a deliverable.
