   ThemeSync Subscribe — frontend styles
   All values pull from CSS custom properties injected by the active theme
   (see TS_Sub_Themes::css_variables()). Selectors are doubled to lift
   specificity above common theme styles. !important is used sparingly on
   sizing and typography where theme interference is most frequent.
