Two grid placement bugs: 1. Items with explicit column but auto row (e.g. `grid-column: 2`) were hardcoded to row 0 by merge_placements, causing overlap with earlier rows. Now only fully-specified placements skip auto-placement, and Phase 2 respects explicit column/row constraints. 2. Negative grid line numbers were off-by-one. CSS Grid has N+1 lines for N tracks, so line -1 should resolve to index N (after the last track), not N-1. This caused `grid-column: 1 / -1` to span N-1 columns instead of all N, producing asymmetric gutters. Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>
