/* ==========================================================================
   Forms — Verity-wired inquiry forms (Home sidebar, Inquire, Contact, Tour,
   Military). Accessibility is the priority here.
   A11Y:
     - Every control has a <label for> association (no placeholder-as-label).
     - Required fields marked with a text asterisk + "(required)" in the label,
       AND aria-required — color is never the sole signal.
     - Errors are surfaced inline, linked via aria-describedby, and announced
       through an aria-live="assertive" region per field group.
     - Inputs meet 44px min target height and ≥3:1 border contrast.
