/*
 * DamageBrief — the app's theme over vendored Bootstrap 5 (dark) and its shell: the desktop sidebar, the phone top bar
 * and bottom navigation, the content column. The component layer (page headers, cards, chips, stacked tables, the
 * analysis stepper, skeletons, toasts…) is components.css, loaded right after this file. The brand palette and the
 * Inter font faces live in brand.css (loaded first). No inline styles anywhere in the app (strict CSP).
 *
 * CONTRAST (WCAG 2.2 AA, measured on every view by test/test_helpers/ui_quality.rb#assert_contrast_aa in the system
 * lane's ui_*_test.rb): every text colour below meets 4.5:1 on the
 * surfaces it is used on. Two choices follow from that and are deliberate: filled primary buttons use blue-600 (white
 * on blue-500 is 4.0:1, under the minimum), and "faint" text is slate-400 (slate-500 is 3.6:1 on the page).
