/**
 * Design tokens: an iOS-style grouped palette with orange as the one accent, in the style of the
 * Claude Account Manager app.
 *
 * - `--accent` fills buttons, rings and bars; `--accent-text` is the darker orange for text on light
 *   surfaces (5.2:1 on white), since the fill orange alone is too light for small text.
 * - Cards are "lux" panels: a top highlight, a hairline ring, a close shadow and a wide soft one.
 * - Poppins first; Be Vietnam Pro fills in the Vietnamese letters Poppins lacks (ạ, ơ, ư, ễ…).
