These are the reasoning phases Leo already moves through. In production the phases are already real — each is surfaced as status text in the reasoning timeline (e.g. "Leo is thinking…", "Analyzing activity data…"). What Tier 1 adds is a distinct icon animation per phase. Today the icon only has two modes: a breathe, and orbiting dots while a streaming artifact builds.
Use the A / B / C toggles to compare options for each state. Open the Sequence player (bottom-right): Recommended Set (tour) shows the full set at an easy pace, and the scenario flows (Quick answer, Data + chart, Report, Error + recovery, User stops) play at rough real-world timings so you can judge whether each animation reads at speed. Different prompts surface different phases — a simple ask is 2 phases; a report runs several. Transient signals (error, stop) fire once; ongoing states loop. (Timings are estimates — real phase durations still TBD.)

Use the A / B / C toggles on each Tier 1 card to compare animation options.
Open Sequence → Production Flow (Tier 1) to watch your selected A / B / C picks play through a real flow — the star holds one size throughout; only the motion and the status text change per state.
Note: Completion is not a Tier 1 state — every Minimal state rests at the same neutral star between beats, so when reasoning ends the star simply hands off to the static sparkle already sitting next to the answer (no separate exit animation needed). See the (i) button for the leoPhase wiring table.
The Claude agent (segment flag agentPathFlag) renders a step-by-step
activity timeline instead of the single reasoning line. Per an earlier decision,
Tier 1 brings the bare star onto this surface too — steps shown beneath, collapsing to a
"Reasoning" toggle when done (also a reviewer's "steps beneath" ask). Mock only; real data needs the flag + Claude backend.
Instead of forcing the bars into the 36px chat gutter, the crowd-favourite viz motion lives
inside the chart artifact card as its loading skeleton — bars build in-place, then resolve into the
real chart. Real canvas, semantically honest (a chart is forming here), and it’s a reviewer’s "match loading anims
with visualizations" ask. Mock only; needs the chart to stream a started signal so the card mounts empty first.
Add a leoPhase computed in reasoning-panel.vue (or pass from conversation). Map each phase to a Minimal CSS class on sparkle-icon.vue.

Production today: only two icon modes exist — :breathing (pending, not streaming artifact) and :orbiting (streamingArtifact). Tier 1 adds distinct animations on top of signals that mostly already exist; error/stop need new wiring.
Completion is not a state. On pending → false the animated reasoning icon unmounts and the persistent static sparkle in message.vue takes its place (same spot, next to the answer). Because every Minimal state is authored to rest at the exact neutral star (scale 1, no glow) at its cycle boundaries, this handoff needs no dedicated exit animation — the star is already at rest between beats, so the swap reads clean. No settle step required for Tier 1.
The Minimal tab animations are production-ready today, following the same pure CSS @keyframes pattern already used in sparkle-icon.vue. Add a :state prop + the corresponding CSS class. No new dependencies.
The Exploration tab states that use extra elements (rings, nodes, bars) need a light wrapper component, but still require zero JS animation libraries.
Currently using CSS cubic-bezier, which approximates spring behavior. For a more organic, "alive" feel, especially on state-to-state transitions. Consider motion-v (Vue-native port of Framer Motion, 18 kb, MIT).
Best applied to transitions between states, not ambient loops. Ambient loops are already well-served by CSS.

Claude uses an orange sunburst, ChatGPT uses a single pulsing dot. Both are branded minimal indicators. This showcase follows the same pattern. A 2025 Stanford study found moderate-speed animations cut perceived wait time by 15–20%.
100% of major AI products include a Cancel / Stop control. Collapsible reasoning traces (e.g. Claude's "Thought process") are the next emerging pattern to watch.
Respect prefers-reduced-motion in production. Pause or simplify loops when the media query fires. Use a single aria-live="polite" region for state announcements rather than announcing every token.
