Living Type

Agentic typeface: the words an agent supplies are set glyph by glyph on canvas and every letter breathes on its own noise track -- drifting, tilting and scaling a little, so the headline feels alive rather than animated. Letters lean toward the pointer and swell as it passes. Works on light or dark backgrounds (set background and colors). Honours prefers-reduced-motion (renders one static frame), pauses offscreen, DPR-aware; the words are also emitted as visually-hidden text. Sibling of particle_type and light_type. Every option is an enum or a clamped int; text is JSON-encoded into the script with "<" escaped.
