/* openhouse-mhe · MHE canonical brand (v1.0)
 *
 * Follows /Users/megroberts/Desktop/Meg - Drop/Matthew Hoult Estates/
 *   next-phase-design-system/css/design-tokens.css (imported).
 *
 * Pattern = "Private intake card", single page (no carousel):
 *   Paper ground · Sand card · mono index header · bottom-rule fields ·
 *   square corners · terracotta CTA · mono system voice.
 *
 * Open-house variant notes: this is filled standing up, on a phone or a
 * propped iPad, by someone who wants to go look at the house. Tap targets
 * are oversized, the yes/no branch is a pair of plates rather than radio
 * dots, and conditional blocks animate in so the page never feels long.
