   RiGeBa Lighting — Home v2
   Scoped under .hv2-* so it can coexist with style.css (no global overrides).
   Used by: home-v2.html
   Design notes
   - Factory product shots are studio photos on WHITE backgrounds. On a dark
     UI they read as glaring white boxes, so every fixture sits on a light
     "spotlight plate" and the photo blends into it with mix-blend-mode:
     multiply. Keep isolation:isolate on the plate or the blend leaks.
   - No emoji icons anywhere; visual weight comes from type, light and photos.
