Evidence

• Before: verifying feat: drag a Block Type from the Block Palette onto the Worksheet #6 took about ten calls to find a working browser setup. A leftover pnpm dev held port 1420 and blocked pnpm tauri dev.
  After: the recipe, the LD_LIBRARY_PATH fix, the WebKitGTK path and the cleanup rule are written down.

Docs only. Pre-commit (lint, typecheck, tests) passed.

Merge Danger

Door: two-way

Blast Radius: Agent docs

testing-dnd.md references src/components/palette-drag.test.tsx, which lands with #17. Merge #17 first.
