/*
 * Site-wide responsive layer, loaded last by base.html.
 *
 * Every rule is inside a small-screen media query, so desktop layouts are
 * untouched. Page templates carry their own <style> blocks (loaded after
 * this file), so selectors are prefixed with `body` for enough specificity,
 * and !important is used only where templates set inline styles.
 *
 * Covers the shared building blocks: page headers (Back / title / action
 * button), the .container-fire / .container-plant-m page cards, Bootstrap
 * accordions used by the long forms, card/section headers, Select2 and
 * DataTables, plus media that would otherwise overflow the screen.
 */

/* ---------- Page banners (all widths) ----------
 * Nine pages (pending alerts, control-room pages, submitted/edit lists,
 * create user, gap analysis) draw their banner as `.page-header` straight
 * inside .wrap with position: fixed, centred on the window. It ignored the
 * sidebar (sliding underneath it), and the page compensated with a 100–200px
 * top margin and an inner scroll box under `html, body { overflow: hidden }`.
 * Pages whose header lives inside their own container are not matched.
 * The site navbar is position: fixed, so the banner starts below it;
 * base.html keeps --fw-nav-h set to the navbar's real height (it is shorter
 * on phones and grows when the mobile menu opens). */
