Template libraries are technical debt you import on purpose

Template libraries are technical debt you import on purpose
That 700-template kit is a feature in the sales page and a liability six months later.

— Most pro kits assume a specific builder version; update the builder and spacing drifts.
— Imported templates carry their own global colors and fonts, often duplicating yours.
— One kit I imported registered 14 extra Google Font weights I never used.

Pros: instant structure, good for pitching layout ideas fast.
Cons: font bloat, duplicate globals, version coupling, hard to audit later.

Best for: wireframing and client demos. Strip the template down to your own globals before launch, never ship a kit page as-is.
