/*
  Force Measurement dashboard (Version 3 Phase 1 — Force Plate).

  Loaded alongside styles/v3-app-shell.css in v3.html (after it, so the
  --v3-* custom properties it defines are already in scope) — this file
  never redefines them and never touches css/styles.css, the legacy Phase
  9.7 stylesheet. Scoped entirely under .v3-fm-* / [data-force-measurement-*]
  selectors so it can never bleed into the rest of the shell.
