## Provisional visual-only Lv1..3 study. Preserve the existing two bed anchors,
## footprint and operation overlays. These are cosmetic pixels, not new game
## costs, capacity, quality or upgrade rules. Level1 draws no added rectangles.
## Existing 16px furniture palette is retained. Inspected Kenney references and
## exact CC0 records are pinned; no narrow two-bed replacement was selected.
