/* ==========================================================================
   BioWave — main stylesheet (biowave.fun)
   Theme: "Bioluminescent tide" — deep abyss teal that gets darker as you
   scroll down, glowing aqua-mint plankton light, sunset coral and sand.
   Niche: marine life & ocean exploration (species, ocean zones, dive
   destinations, reef conservation) — a crew/community site, not a link-in-bio tool.
   Every class is prefixed "bw-" so nothing clashes with admin/Bootstrap CSS.
   Animations use transform/opacity only.
   Signature patterns are unique to this site — see Notes/Workflow/Design Registry.md.
