## Problem
six apps had no shared lint checks for invalid tailwind classes,
off-scale values, and raw colors.
## Solution
add @shadcn/lint warnings with narrow exceptions for existing theme
colors and artwork. fix several invalid classes. the existing lint
command reports findings without blocking prs on the current warning
count.
## Review instructions
1. check the shared rules and app-specific exceptions.
2. run `pnpm --filter design-system lint` and confirm it reports shadcn
warnings without errors.
