     FRAGMENT PERFORMANCE LAYER STRUCTURE
     ============================================================================
     
     Layer hierarchy (from bottom to top):
     
     #editor-container
     ├── #editor (z-index: default) — The actual editable text area
     └── #overlay (pointer-events: none) — Non-interactive visual layer
         ├── .fragment-text-wrapper
         │   ├── #bottomLayer (z-index: 0)
         │   │   └── .fragment-text.bottom-text — Original/unmodified text
         │   ├── #layer-0 (z-index: 1)
         │   │   ├── .fragment-text.layer-text — Synonymized text (1st synonyms)
         │   │   └── .glass-overlay — Blur effect
         │   ├── #layer-1 (z-index: 2)
         │   │   ├── .fragment-text.layer-text — Synonymized text (2nd synonyms)
         │   │   └── .glass-overlay — Blur effect
         │   └── ... (n layers, each with increasing z-index)
         └── .control-points-layer (z-index: 100) — SVG with draggable points
     
     How it works:
     - #editor: The contenteditable area where the user types
     - #overlay: Sits on top of editor, passes through pointer events
     - #bottomLayer: Shows original text, no clipping (full area)
     - #layer-N: Each layer shows text with Nth synonym for each word,
       clipped to a triangle via CSS clip-path: polygon(...)
     - .glass-overlay: Inside each layer, applies backdrop-filter blur
     - .control-points-layer: SVG overlay with 3 control points per layer
       (color-coded to distinguish which layer each point controls)
     
     Visual effect:
     - Original text visible everywhere (from bottom layer)
     - Each triangle fragment shows different synonymized text
     - Higher z-index layers appear on top of lower ones (no blending)
     - Drag control points to reshape each layer's triangle
