+# `@proj-airi/stage-ui-tachie`
+
+Tachie scene rendering for characters represented by a small set of complete,
+static emotion images.
+
+## What it does
+
+- Loads `.tachie.zip` archives from local files, blob URLs, or HTTP(S) URLs.
+- Selects images through AIRI's shared emotion vocabulary.
+- Renders the active image with PixiJS on a transparent, responsive canvas.
+- Persists scale, position, render scale, and theme-colored shadow settings.
+- Exposes canvas capture for stage screenshots and theme-color extraction.
+
+## Archive format
+
+`neutral` is required. Every other image is optional, and missing emotions fall
+back to `neutral`. File extensions are not part of the protocol; image content
+only needs to be decodable by the browser.
+
+```text
+character.tachie.zip
+├── neutral.png
+├── happy.webp
+└── surprised.jpg
+```
+
+A single wrapping directory is also accepted:
+
+```text
+character.tachie.zip
+└── character/
+    ├── neutral.png
+    └── happy.webp
+```
+
+Supported names are `neutral`, `happy`, `sad`, `angry`, `think`, `surprised`,
+`awkward`, `question`, and `curious`. Matching is case-insensitive. Every
+recognized image must use the same pixel dimensions.
+
+## How to use
+
+```vue
+<script setup lang="ts">
+import { TachieScene } from '@proj-airi/stage-ui-tachie'
+</script>
+
+<template>
+  <TachieScene :model-src="modelUrl" />
+</template>
+```
+
+## When to use it
+
+Use Tachie for low-asset characters whose visual state can be represented by
+one complete image per emotion.
+
+Do not use it for layered sprites, rigged animation, lip-sync, or parameterized
+eye and body tracking. Use Live2D, Spine, VRM, or MMD for those models.
