   BOUNCING BLOBS BACKGROUND
   Animated colored circles that drift across the viewport,
   blurred by a glass overlay. Two modes:
   - data-blob-mode="palette" (default on main page): per-blob
     classes determine colors (orange/green/teal/...)
   - data-blob-mode="accent" (project pages): all blobs share
     --c-accent-rgb (must be set as "R G B" triplet on :root)
