   LUG GLASS — the one LevelUpGrowth platform stylesheet (concept v1)
   Every surface (web app, admin, desk, marketing, standalone pages, emails
   via build step, companion app via generated tokens.ts) reads THIS file.
   Rules: no module CSS, no <style> in views, no inline style="" except
   layout-free custom properties. Anything new becomes a token or a class here.
   Brand spine = the logo gradient: violet #8C25D2 → blue #4C86DE → aqua #3FDFDF
