/*
  PLAT-013 — the generic form-renderer stylesheet. Device-agnostic, RTL-safe, WCAG-aligned, and entirely
  domain-free (no pack/vertical selectors; everything keys off the structural kf-* classes the renderer emits).

  Mobile/Responsive First (PRD §PLAT-013A):
   - columnCount drives an N-column CSS grid on desktop via the --kf-columns custom property; at the 600px
     mobile breakpoint the grid REFLOWS to a single column (WCAG 1.4.10 reflow — usable at 320px with no
     horizontal scrolling). Logical reading order is preserved because DOM order == declared order and we
     never CSS-reorder.
   - RTL/bidi: ALL inset/spacing uses LOGICAL properties (margin-inline / padding-inline / inset-inline-start)
     — there is no hardcoded left/right anywhere — so the layout mirrors under dir="rtl". LTR data embedded in
     RTL UI (IDs, coordinates, case numbers, timestamps) is bidi-isolated.
   - WCAG 2.5.8 target size: interactive controls are >= 44x44 CSS px on every platform.
