    /* IMPORTANT: the VBO plugin's vri-vikbooking.css defines --vri-font-body
       as the font-SIZE (14px), so we can't use that name for the family.
       We use --vri-font-family-body / --vri-font-family-nav here instead.

       Stack rationale (in order):
         -apple-system, BlinkMacSystemFont, 'SF Pro Text'
           → Apple platforms render SF Pro Text natively, no download.
         'Inter'
           → cross-platform fallback for Android/Windows/Linux. Inter was
             designed by Rasmus Andersson to look like SF Pro and is the
             industry-standard SF lookalike (loaded from Google Fonts).
         system-ui, 'Segoe UI', Roboto, Helvetica, Arial, sans-serif
           → final fallbacks if the Inter request fails entirely. */
