/* ============================================================================
   v3-shared/enquiry.css — shared component layer for the Harbour release
   candidate (Combined Air-Con & Electrical).

   Loaded AFTER designs/v3-harbour/style.css on both index.html and enquire.html.
   It carries the structural + interactive components (masthead, nav, buttons,
   the single-step enquiry form, footer basics) and reads its visual values from
   CSS custom properties the concept sets in its own :root — the same contract
   the v2 layer used, so the two rounds stay visually consistent.

   There is deliberately NO booking, calendar, time-slot or file-upload styling
   here: the launch direction is a simple text enquiry (see
   HARBOUR-COPY-AND-ENQUIRY-BRIEF.md). Photos are explained in copy, not uploaded.

   Contract (the concept style.css must define):
     --bg --surface --surface-2 --line --line-strong --text --muted --accent
     --accent-ink --danger --header-bg --header-line --header-rule --logo-w
     --wrap --radius --bw --font-body --font-display --font-mono --label-tracking
