v1.2 - Animated head sprites

What's new

• Animated head sprites. A new animation type sits alongside static sprites and sequences. An animation is an ordered list of frames (each frame is a row of one or more heads) played on a loop at a configurable interval. Animations are stored in sprites.yml and authored in the built-in web editor.
• Chat & MiniMessage tag: use <anim:name> to insert a live, looping animation inline. The <sprite:name> tag also falls back to an animation's first frame when the name matches an animation.
• PlaceholderAPI: new %headsprites_anim_name% placeholder returns the current animation frame as a JSON text component for Skript/custom chat formats.
• Commands: /sprite anim list, /sprite anim display <name> (spawns a looping animated TextDisplay in-world), and /sprite anim stop (removes running displays), all with tab completion.
• Web API: new /api/animation and /api/animation/delete endpoints; animations are included in the editor state.

Install

Drop HeadSprites-1.2.jar into your server's plugins/ folder. Requires Paper 1.21.x and Java 21. PlaceholderAPI is optional (needed only for the Skript/placeholder bridge).
