# Sprite edge cleanup — 1.3.1

The active title, world actors and Luma dialogue portrait now use transparent sprite assets with the cream sticker border and printed exterior shadow removed. The established faces, costumes, colors and poses were used as identity references. These are image-edited versions, not byte-identical originals. Original assets and the earlier editions remain available.

Production assets: `assets/characters-v131/mei.webp`, all six `abby-*.webp` states and all five `luma-*.webp` states. Master cutouts are retained as `*-source.webp` in the same directory. All canvases retain the previous dimensions (Mei 362×537, Abby 374×380, Luma 403×511), using uniform fitting and transparent padding. Existing camera, actor dimensions, animation durations and accessibility settings are unchanged.

Built-in imagegen performed the artwork cleanup. `build_character_variants_v131.cjs` compiles those transparent masters into the same whole-image rotation, scale and offset states as the previous asset recipe. Run it with no arguments to rebuild from the checked-in masters; optional arguments are the three generated PNG paths, in Mei, Abby, Luma order. No color threshold or CSS blend mode is used, so pale socks, fur, skin and wings remain colored artwork.

Generation prompts:

## mei

Use case: background-extraction / identity-preserve. Edit target: the supplied existing game sprite of Mei, the child with the exact dark bob haircut, yellow flower hairclip, yellow hoodie, navy shorts, yellow shoes and brown backpack. Make a production transparent sprite by removing ONLY the off-white paper/sticker border, cream background and exterior printed drop shadow. Trace the actual colored character silhouette accurately; alpha must begin at the hair, fur, clothing, skin, shoe, wing and gold-star edges. Remove the broad pale sticker halo everywhere including inside gaps between limbs, tail, wings and body. The entire canvas outside the colored artwork must be genuinely transparent (alpha zero), never filled black, white or a checkerboard. Keep fine fur tufts and whiskers for Abby, the real pale socks/soles and hoodie drawstrings for Mei, the actual semitransparent purple wings and small gold stars for Luma. No white stroke or bright perimeter glow. Preserve this EXACT face, pose, expression, anatomy, colors, interior illustration details and original orientation. Do not redesign, relight, add effects, repaint as a new character, or add text. Keep the original full-body composition and original canvas aspect ratio, leaving a small transparent safety margin. This is precise sticker-border removal from an established character, not a new illustration.

## abby

Use case: background-extraction / identity-preserve. Edit target: the supplied existing game sprite of Abby, the exact fluffy gray-brown kitten with gold eyes and gold bell on red collar. Make a production transparent sprite by removing ONLY the off-white paper/sticker border, cream background and exterior printed drop shadow. Trace the actual colored character silhouette accurately; alpha must begin at the hair, fur, clothing, skin, shoe, wing and gold-star edges.

## luma

Use case: background-extraction / identity-preserve. Edit target: the supplied existing game sprite of Luma, the exact golden-haired fairy with violet translucent wings, lavender petal dress and a few small gold stars. Make a production transparent sprite by removing ONLY the off-white paper/sticker border, cream background and exterior printed drop shadow. Trace the actual colored character silhouette accurately; alpha must begin at the hair, fur, clothing, skin, shoe, wing and gold-star edges.
