Digital Walls — Sprite Calibration Pack v0.2

Eight independent RGBA PNG files for visual testing in Cursor, plus desktop/mobile previews and manifest.json.

Status: calibration prototypes, NOT finalized production assets. Six assets are carefully extracted from the approved concept sheet; two (CD player, neon moon) are independent higher-resolution generations. All have real alpha, but edge cleanliness, sprite grid harmonization, mounted scale, and mobile legibility require QA. Never assume the dimensions shown in concept sheets are genuine export dimensions.

Usage

• Render each sprite as an independent positioned image element (not a baked-in background).
• Use stable logical coordinates (e.g. normalized percentages of the wall plane) and store positions, z-order and scale in board data.
• Avoid applying CSS filters globally; neon glow should be its own optional light layer in a later production revision.
• For crisp pixel-art variants, test image-rendering: pixelated at integer-ish multiples, but inspect the neon glow: it may need smooth rendering.
• Validate on 390px mobile and 1440px desktop.
• For wall mounting, use the per-sprite anchor metadata; surface objects require an appropriate shelf/cabinet surface rather than arbitrary wall mounting.

Next quality gate

Individually regenerate the six sheet-derived objects at higher native detail, validate true transparency and clean silhouette, standardize pixel grid / common pixel-unit, export material variants, then confirm visual fit across plaster, whitewashed brick and light-concrete environments.
