- A. compute_zone_layout_cols (1건): Task 11d min-width floor(≤260px) 계약으로 갱신
- B. build_layout_css fixtures (3건): floor 반영값으로 재생성 (fixture refresh = 설계된 lock surface)

Stage 3 lock implementation: extend build_layout_css dispatch beyond
the horizontal-2 / vertical-2 1-D dynamic paths. T / inverted-T /
side-T-left / side-T-right / 2x2 now flow through a 2-D track solver
instead of the fr_default sink, with length-locked heights_px (R) +
widths_px (C) on every return path (default and override).
PR 2 scope (u1~u5):
- u1: _aggregate_zone_signals_per_track — per-row + per-col virtual
zones via max(weight) + max(min_height_px) of single-span zones,
falling back to all-span when a track has none.
- u2: _build_grid_dynamic_2d default builder — feeds virtual zones
into compute_zone_layout + compute_zone_layout_cols; emits
computation="2d_dynamic_aggregated", dynamic_rows=True,
dynamic_cols=True.
- u3: _override_to_grid_tracks override builder — single-span
aggregation (max h per row, max w per col), normalize, multiply
by avail_h/avail_w, last-element diff absorb; emits
computation="user_override_geometry"; falls back to u2 when
total_h or total_w == 0.
- u4: build_layout_css dispatcher wiring — topology in
{T, inverted-T, side-T-left, side-T-right, 2x2} routes to
_build_grid_dynamic_2d (default) or _override_to_grid_tracks
(override); legacy [override-warning] stderr removed for the
5 presets; step08 trace gains a 2-D-aware print line that fires
before the dynamic_rows / dynamic_cols branches.
- u5: PR 1 lock test test_top_1_bottom_2_fr_default_populates_geometry
renamed to test_top_1_bottom_2_dynamic_2d_populates_geometry and
flipped to PR 2 reality (computation="2d_dynamic_aggregated",
dynamic_rows=True, dynamic_cols=True).
Fixtures: 10 build_layout_css (5 presets × {default, override}) +
5 retry_gate *_dynamic_2d.yaml locking the retry gate skip reason
"dynamic_cols (2-D topology) ... IMP-09 lock" for the 5 presets.
