/* =============================================================================
   Alabama Signature Homes — services/house_plans
   =============================================================================

   The house-plans service page, app/views/services/house_plans.html.php: a
   third-party iframe with a skeleton behind it while it loads.

   ORDER MATTERS in this file. .plans-skeleton__rail is declared twice, and the
   second declaration (width: 300px) overrides the first (min-width: 200px).
   Same layer, same specificity, so source order is the only thing deciding it —
   the two halves were adjacent blocks in main.css and must stay in this order.

   Same house rules as main.css — no nesting, flat selectors, media queries
   inside the layer that owns them. Everything is wrapped in @layer: an
   unlayered rule would outrank even the utilities layer.
