/*
  TERACO.LABO White Theme Override
  - Keep blue→green gradient as accent
  - Shift overall base to white, reduce heavy glass/blur
  - Do not alter content/structure; style-only overrides
  - Add mobile-friendly defaults shared across all pages
  - Modern minimal UI to match logotype (fonts + outline buttons + chips)
