/**
 * forms.css — shared visual language for the contact, job application,
 * appointment and calculator forms, built on top of resources/views/components/form/*.
 *
 * Colours and radii come from the FFC design-system tokens (tokens.css,
 * Phase 4): controls and buttons share --radius-sm, surfaces/ink/borders use
 * the semantic tokens, errors use --status-danger as text + border only
 * (never a fill), focus is a 2px --border-brand outline plus the --focus-ring
 * halo (--status-danger on a field in error). Control boundaries use
 * --neutral-500 (3.72:1 on white, WCAG 1.4.11). 62px min control height is kept. Usage: docs/DESIGN_SYSTEM.md
 *
 * Works unmodified in both locales: Arabic is RTL at the root, English is
 * LTR under /en (dir on <html>). Every rule below uses
 * logical properties (inline-start/end, text-align:start) instead of
 * left/right so no ltr/rtl override file is needed for this stylesheet.
