/*
 * App shell: page layout, masthead + search, tabs, panel / mobile bottom sheet, footer, map chrome.
 * Components rendered by MK.ui live in components.css; dialogs in dialogs.css; tokens in tokens.css.
 *
 * Desktop (>= 900 px): 420 px sheet column on the left (masthead above the panel), map fills the rest.
 * Mobile: full-screen map, floating search card on top, bottom sheet with peek / half / full snap points
 * keyed on #panel[data-sheet-state] (set by MK.ui.sheet or the app.js fallback; --sheet-drag while dragging).
 *
 * The page itself never scrolls: #panel-body is the only scroller and the containing block of everything
 * absolutely positioned inside it (visually hidden captions, radio inputs), and .app clips to the viewport.
 * Without that, those elements escaped the scroller, grew the document, and focus()/scrollIntoView()
 * scrolled the viewport (masthead pushed off-screen) although body has overflow: hidden.
