/* public/css/topbar.css
 *
 * Top bar: brand, location/status line, and the co-equal filter chips.
 * Theming rides entirely on the CSS variables defined in base.css (light + dark
 * safe). The five quality dimensions are co-equal here -- every chip shares one
 * neutral resting style and one identical active treatment. Price gets no
 * special size, color, or position. No '$' framing anywhere.
 *
 * Quality color tiers (great/ok/poor) are NOT used in the top bar: the chips are
 * selectors, not scores. Those tiers live on markers, badges, detail, and
 * rating, used identically there.
