/* Solid Data brand overlay for LibreChat.
 *
 * Mounted and loaded AFTER the compiled app bundle so these custom
 * property redefinitions cascade over LibreChat's defaults
 * (client/src/style.css, selectors `html` / `.dark`) without forking or
 * rebuilding the LibreChat image. Only the semantic tokens LibreChat
 * exposes as CSS variables are covered here, plus the `.btn-primary`
 * component class (send button), which hardcodes rgba() values instead
 * of reading a variable.
 *
 * Known gap: any other hardcoded color (not a variable, not
 * `.btn-primary`) will NOT be caught by this file. Do a visual pass
 * after deploying (light + dark mode) and extend this file if anything
 * still shows LibreChat's default green/purple.
 *
 * Palette source: solid-data-brand skill.
