# Prototyping parity

> **Last reviewed:** 2026-10-10 · **Last updated:** 2026-10-10 · **Change:** major (created; triggers, actions, transitions and easings counted from `crates/doc/src/proto.rs`) · **Target:** Figma Design (desktop app 126.10.7)

**Breadth ~88%, ready ~70% (estimated).** Every Figma trigger except media and gamepad, every
action except media control, every transition and easing exist (measured from the model enums on
2026-10-10). Not yet checked against larger real prototypes. Remaining: 5–9 h.

| Actions | Navigate to, change to, back, scroll to, open link, open / swap / close overlay, set variable, set variable mode, conditional, play/pause/mute/seek media | 11: Navigate, Back, ScrollTo, OpenOverlay, SwapOverlay, CloseOverlay, OpenUrl, ChangeTo, SetVariable, SetVariableMode, Conditional | media actions |
| Transitions | Instant, dissolve, smart animate, move in/out, push, slide in/out | all 8 | — |
| Easing | Linear, ease in/out/in-and-out, back variants, gentle, quick, bouncy, slow, custom bezier, custom spring | all 13 | — |
