/* ekg-bot — house guide widget (fleet canon, 1.0.2).
   Every colour, font, radius and shadow is an --ekgbot-* custom property with a neutral default, declared under
   :where(.ekgbot) so it carries zero specificity: a site maps its own design tokens with a plain `.ekgbot { … }` rule
   in its theme and wins regardless of load order (and dark mode follows whatever the site's tokens do). Sites may also
   pass their own stop-callout classes through config.classes; .ekgbot__stop below is the fallback. */
