## How to reapply — copy this exact dict, don't reconstruct it from memory

This is the complete, current correction set (all 20 parts). **Copy-paste
this block, don't retype it from the table below or from memory** — the one
time it was retyped from a section of prose instead of copied whole, U4 got
silently dropped and shipped with a wrong rotation.

to F.Cu; they now take **+180°** and live in the corrections table (green
