/* ==========================================================================
   estimator.css: the project estimator widget (markup built by js/estimator.js).

   1. Tokens (neutral defaults; each theme overrides them at the bottom)
   2. Layout, mobile first: options stacked above the result ticket; from a
      ~54rem-wide container, options left and a sticky result ticket right.
      Components size themselves with container queries, so the widget reflows
      cleanly at any width and while the window is being resized.
   3. Components: questions, platform tiles, feature chips, size segments,
      design pills, the result ticket, plans, the math, send button, notes,
      phone peek bar
   4. Theme skins, each scoped to :root[data-theme="…"]:
        diner    = a diner order pad / guest check
        forest   = a ranger's field logbook / park fee sheet
        airfield = a flight manifest / boarding pass
   Every class starts with "est". Checked states never rely on colour alone:
   each option shows a check mark when it's on.
