theme.mode wrote data-theme-mode to the DOM but no CSS ever reacted to
it, and mapThemeConfigToCssVariables() never looked at mode at all -
selecting Dark had zero visible effect.
Added dark-mode neutral overrides (background/text/border axis only -
brand colors stay as configured) using the palette provided by the
user (colorhunt.co/palette/091413285a48408a71b0e4cc):
--bg-primary: #091413 --bg-secondary: #285a48
--text-primary: #b0e4cc --text-secondary: #408a71
--border-color: #285a48
ThemeEngineService now resolves 'system' mode via
prefers-color-scheme and re-renders live on OS theme changes, and
sets data-theme-mode to the *effective* resolved mode instead of the
raw setting.
