Day 3: Passes 148-170 — Polish Sprint

Final day of the pipeline sprint. 23 passes focused on polish and the last blockers.

Fixed the PreFight screen collapse — root cause was a plain Transform serialized as !u!4 instead of RectTransform !u!224 in the scene file. One wrong Unity component type, and the entire layout collapses to a single pixel.

Scaled up all Training screen UI elements 30-50% for mobile readability. 32 individual sizing edits in one pass. Replaced 873 smart apostrophes across 36 JSON files that were causing missing glyphs. Built a full save migration framework.

By end of day: 170 total passes, 13 nuclear layout rebuilds all complete, 25/25 stale singletons fixed, 0 compile errors.
