## What kind of change does this PR introduce?
UI copy + agent guidance.
## What is the current behavior?
- The Table Editor labels the Data API setting as "Data API Access"
(title case).
- Agents have no scoped pointer to our copywriting rules
## What is the new behavior?
- Label uses sentence case: "Data API access" (e2e and test docs
updated).
- Agents are pointed at
`apps/design-system/content/docs/copywriting.mdx` via
`studio-copy.instructions.md` and `studio-ui-patterns` skill.
