## Summary

- Remove the completed Superpowers implementation plan and the artificial editable-prose probe from the development gallery. - Drop browser and unit checks that only repeated fixture inventory, CSS source strings, or error-hint wording. - Keep renderer security and boundary tests, multi-instance interaction checks, keyboard scrolling, reduced motion, and page overflow coverage. Generated edge IDs now need to be unique and agree between SVG and graph metadata, without fixing their spelling.

## Preview


The development document specimen now shows its diagrams without a test-only editable field between them.

## Checks

- The original PR head passed `bun run fix`, `bun run ci`, `bun run types`, and `bun run build`. - Focused diagram unit tests: 16 passed on the original head. - Gallery browser suite: 9 passed, 1 intentional wide-view skip on the original head. - Production gallery exclusion: verified across 415 built assets on the original head. - The two feature commits replayed patch-identically onto the prepared stack without the old merge commit. Local preflight on that linear branch passed focused maintenance and diagram tests, `bun run ci`, `bun run types`, and `bun run build`. Required GitHub checks will rerun after the final rebase.
