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

Mark this Space as redirected to bing-yan/spark

Rebrand TRACE -> SPARK

Joint Phase-2 OOD heads + missing runtime modules

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

Expand mechanism full-name labels (CV: 9 ID + 4 OOD; TPD: 11 ID + 2 OOD)

Ship generate_extended_mechanisms.py so CE/EE/EC_prime/ECE/EC_LH/MHC_EC/MHC_LH reconstruction works

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
