/* ============================================================
   HRG1000 product page: COMMON STYLESHEET
   All page styles live here. index.html has no inline CSS.
   1. Layout & components: grouped by page section, one class per look
      (search the class name in index.html to find the element)
   2. Interactive states: gallery thumbs, units toggle, form status
   3. Responsive & page overrides: breakpoints, stat strip, hidden header/footer
      (kept last so these rules win)
   Brand tokens (colours, fonts, spacing) come from the hoffer-*.css files.
