/* Revolutionary Chat Bot, frontend styles.
 *
 * The accent color is injected via an inline <style> as --rcb-accent, with
 * three companions computed in PHP (RCB_Plugin::accent_palette()):
 *   --rcb-accent-contrast  text drawn ON the accent (black or white)
 *   --rcb-accent-ink       accent-colored text on white, or dark text when
 *                          the accent is too light to read (gold, yellow)
 *   --rcb-accent-ring      translucent accent for focus shadows
 * The accent itself is only ever a fill, border or underline.
 *
 * Surfaces and text use --rcb-* tokens. When the theme runs a color mode
 * (html[data-color-mode], multipurpose-theme 1.48+) they follow its
 * --dash-mode-* palette, so the panel is readable in light and dark mode.
