/* ── CField · Latih EKG work area ────────────────────────────────────────────
   The standalone LatihEKG stylesheet, scoped to `.ecg-app` and re-themed into
   the CField sign world: Fira Sans, 3px ink keylines, 2–3px corners, no
   shadows, no gradients, 44px targets, signage labels at the 11px floor.
   Scoping is deliberate: the module shares class names (.card, .chip, .tag,
   .btn) with the CField shell, so nothing here may leak outside the page. */
