+truth.
+
+**Shared across both armies — this is the one sheet that does NOT get the "paint every army's
+sheet in its own finished colours" treatment** from the top of this doc. There's a single
+`icons` entry in the artwork JSON, not an `arm-icons`/`core-icons` pair, and the same frame
+renders in either player's build menu. Paint it in a neutral palette (dark plate + light
+linework is what the procedural fallback already does) rather than ARM blue or CORE red/orange.
+
+**Wired into the build menu** (`TAHud._drawGrid`, since 2026-08-16): every button in the
+build/production grid — buildings AND units — now draws this sheet's `def.icon` frame above the
+shortened name and cost, at a **36×36 display size**. The command bar (Move/Attack/Patrol/…)
+still renders text-only for now; its glyphs (frames 20–29) only exist for the procedural
+fallback painter today.
+
+**The 64×64 source is intentionally bigger than that 36×36 display size.** Painting at exactly
+the display size (the old 44×44 spec was already close to that trap) means every icon gets
+upscaled a little and softens; painting bigger and letting Phaser scale down is what keeps it
+crisp. Draw at the full 64×64 canvas — don't pre-shrink your art to "look right" at a smaller
+preview size.
 
 | Frames | Contents |
 |---|---|
 | 0–9 | Units: commander, infantry, sniper, jeep, tank, rocket tank, rocket trooper, construction vehicle, fighter, bomber |
 | 10–16 | Buildings: energy gen, mass gen, barracks, vehicle plant, laser tower, missile launcher, advanced vehicle plant |

+
+### Painting priority: buildings the Commander and Construction Vehicle put up
+
+This is the set that actually appears in the build-menu grid during a normal game — the union
+of everything `commander`, `constructor` and `hoverconstructor` can build — in a sensible
+painting order (the 8 the Commander itself can queue from turn one, then the 3 that need a
+Construction Vehicle or Hover Constructor first):
+
+| Frame | Building | Also needs a Constructor? | Footprint |
+|---|---|---|---|
+| 10 | Energy Generator | no — Commander builds it too | 2×2 |
+| 11 | Mass Generator | no | 2×2 |
+| 12 | Barracks | no | 3×3 |
+| 13 | Vehicle Plant | no | 3×3 |
+| 14 | Laser Tower | no | 1×1 |
+| 15 | Missile Launcher | no | 2×2 |
+| 18 | Airfield | no | 3×3 |
+| 19 | Radar Tower | no | 2×2 |
+| 16 | Advanced Vehicle Plant | **yes** | 4×4 |
+| 30 | Advanced Radar | **yes** | 2×2 |
+| 31 | Radar Jammer | **yes** | 2×2 |
+
+Draw each as a simplified, high-contrast read of its full structure-sheet art (see Structure
+sheets below), not a literal crop of it — a 128–192px building shrunk straight down to 64px
+loses its silhouette to surface detail. Keep the same silhouette and colour language (Laser
+Tower's plinth-and-emitter, the Radar family's dish/mast/broken-rings distinction, etc.) so an
+icon and its full-size building are still recognisably the same thing at a glance.
