Fix reconstruction unavailable: SIGALRM timeout only on main thread (Gradio runs callbacks in worker threads)

Frontend redesign: branded hero header, Soft theme + CSS cards, decluttered two-column layout, polished plots, grouped examples

Interactive mechanism selector: reconstruct + inspect posterior per chosen mechanism

Switch demo to calibrated RQ-NSF (no sbi, fast load/sampling); add synthetic test examples; trim reconstruction cost

SPARK v4 outer-sphere ET demo (continuous-manifold model + alternative mechanisms)

Fix page header: SPARK acronym expansion (was leftover TRACE)

Rebrand TRACE -> SPARK

Phase-2 joint image+waveform models + From-Image hybrid pipeline

From-Image: gallery shows the input plots (not pre-rendered outputs); add note that digitized curves often trigger OOD

Add OOD detection (CV+TPD), 9 CV / 11 TPD ID demos + 4 CV / 2 TPD OOD demos, scan-rate doc

Posteriors: legend for mean/median markers; footer: drop Built at MIT

Rename: Amortized Chemistry Estimation -> Amortized Conditional Estimation

Header subtitle: expand TRACE and TPD acronyms

UI polish: card layout, per-mechanism detail tabs, mode radio

Initial TRACE deployment: rebrand from ECFlow + noise-aug headline checkpoints
