/* BarrierLedger web-app mockup styling — illustrative screens, fictional demo data.
   Light mode, Inter, FEEC navy accents; semantic status colours only for status.

   Inter is bundled in fonts/ so a screen renders identically on any machine, with or
   without a system copy: Inter v4.001 (git 9221beed3), SIL Open Font License 1.1
   (see fonts/OFL.txt). The woff2 files are local to this directory — no network fetch.
   All six weights the screens compute are bundled (400/500/600/700/800/900); 900 is
   real, not decorative: <b> inside a 600-weight chip resolves `bolder` to 900, pinned
   below so a change to .chip's weight cannot silently change those digits.
   Font independence is checkable — hide the system face and re-run:
     FONTCONFIG_FILE=$PWD/fonts/no-system-inter.conf node ../check_layout.mjs

   Layout contract (fixed 1440x810 still image, rendered by check_layout.mjs):
     nav 54px + page (flex, min-height:0) + footer 28px.
   The page never scrolls: every card's content is sized to fit its box, cards use
   min-height:0 so a flex/grid parent can constrain them, and the checker fails the
   build on any spill, text collision, off-canvas element or content under the footer.

   Spacing scale (only these values are used for gaps and padding):
     2 · 4 · 6 · 8 · 10 · 12 · 14 · 16 · 20 · 22
   Type scale: 10 / 10.5 / 11 / 11.5 / 12 / 12.5 / 13 / 15 / 18 / 22
