## Acceptance Criteria
- [ ] Glyph payloads keep `GLYPH/indexed_v1`.
- [ ] Glyph palette blocks are 4096 bytes.
- [ ] Palette entries are emitted as RGBA bytes in runtime channel order.
- [ ] No synthetic magenta/color-key value is emitted.
- [ ] Size and decoded-size metadata match the new payload length.
- [ ] Scene `palette_id` payload shape is unchanged.
- [x] Glyph payloads keep `GLYPH/indexed_v1`.
