The toolbar's Export button becomes a real menu: Data (JSON) downloads
{ base, panels, results } exactly as held in the store, Per-node CSV
writes one row per panel and node (educated flag, reachedAtRound with
-1 kept), and Picture (PNG) rasterizes each panel's live SVG with the
current theme's token values resolved, drawn side by side with labels
and the live percentage at the current round, plus legend and the
disclaimer footer line, at 2x. Items disable while a run is in flight
so exports always capture settled state.
Per Justin: a round's dots no longer start fading together. Every node
gets a deterministic random appearance moment inside the first 70% of
the round interval (the rest is its fade), and a new roundProgress
value, driven by the playback frame loop, feeds the same jitter into
the panel stats: the big percentage and reached count now tick up
exactly as dots start appearing, in the cards, the mobile strip, and
the focus modal. Pausing, stepping, and seeking hold the full round;
reduced motion keeps discrete swaps.
