   DataCar — single shared stylesheet
   ----------------------------------------------------------------------------
   Every page links this file. Reusable components (public/js/components/*.js)
   also inject a <link> to it inside their shadow roots, so chrome rendered by
   a component is styled by the exact same rules as the page light-DOM content.

   SECURITY NOTE: component markup (logo.js, lang-switcher.js, etc.) is
   ALWAYS static, server-controlled strings. Never build component innerHTML /
   shadow content from user or upstream data — that is the one rule that keeps
   web components injection-safe (see SESSION_NOTES).
