/* falcondatabase — GitHub-inspired UI with light and dark themes.
 *
 * Palette: #ED637D (pink, brand) · #66D7D1 (turquoise, primary) · #FFF87F (yellow, attention)
 *          #F4F1BB (champagne) · #EAF2E3 (alabaster)
 * Dark is the default; light applies with data-theme="light" or when the OS prefers light
 * (unless data-theme="dark"). Every color below is a token, so both themes stay in sync.
