/*
 * common-a.css - Shared styles for all design pages (fixed-header design):
 *   404.html, about.html, cleaning.html, contact.html, flow.html,
 *   services.html, voice.html, faq.html, privacy.html, reservation.html,
 *   tokushoho.html (former system B pages unified on 2026-07-07).
 * Do NOT include on index.html (redirect stub only).
 *
 * Load order matters: common.css -> common-a.css -> per-page <style>.
 * These rules were moved verbatim from the identical inline blocks of the
 * original 7 pages; cascade order against remaining inline rules was
 * verified at property level. When editing, bump the ?v= cache-busting
 * parameter on every <link> that references this file (all 11 pages).
 * Note: reservation.html neutralizes the global 44px min-height on
 * desktop form controls via its inline <style>.
