Agentic typeface: the words an agent supplies are rendered as flowing light -- luminous streams ride a noise field inside the letterforms only (particles spawn on the glyph mask and respawn when they leave it), drawn with additive long-exposure trails and composited through the text as a mask, with a soft glow halo behind. Reads as a headline made of moving liquid light. Pointer swirls the flow. Honours prefers-reduced-motion (one pre-simulated frame), pauses offscreen, DPR-aware; the words are also emitted as visually-hidden text. Dark backgrounds only -- trails are additive. Sibling of particle_type and living_type. Every option is an enum or a clamped int; text is JSON-encoded into the script with "<" escaped.
| Surface | Note |
|---|---|
| Renders as a dark panel; the words remain as visually-hidden text, the canvas is empty without JavaScript | |
| google-chat | Inline script not supported; renders as a solid panel |
| Field | Type | Required |
|---|---|---|
| text | string (required). The words to set, up to 3 lines separated by "\n", each trimmed to 40 characters. Short and bold reads best. Default "A2UI". | required |

| background | "#rrggbb". Default "#070a12". | optional |
| height | integer. Panel height in px, clamped 160-900. | optional |
| interactive | bool. Pointer affects the letters. Default true. | optional |
| density | "low" | "normal" | "high" (optional, default "normal"). Streams per glyph area. | optional |
| speed | "slow" | "normal" | "fast" (optional, default "normal") | optional |
