Upstream gave executive-slate the boreal-style 4x3 icon-grid launcher
while this batch was in flight; the ivory day sibling follows in the
same push so the pair stays shape-invariant. Geometry identical to the
slate grid (pure layout over the ivory rofi.rasi panel; the selected
card keeps the accent-edge highlight).
Verification: V1 here (layout-only file, colors inherited) + the
re-run checks on the rebased tree in this push; launcher grid on real
hardware is already in the batch HARDWARE-QUEUE entry.
