Build on top of v1.8.3-alpha.86. Single-fix release.
The mini-tile grid was strict 2 columns regardless of card width. Now uses repeat(auto-fit, minmax(max(50% - 4px, 140px), 1fr)) so:
- Wide cards: max 2 tiles per row (any 3rd column would need each tile to be >= 50% - 4px wide, which exceeds the row).
- Narrow cards (< ~288 px content width): drops to 1 column so each tile keeps its label readable.
