Better PDB recommendation: the chat scans up to 25 structures per gene before giving up, so genes with large PDB families (TP53, EGFR) show the starred suggestion more often.
Honest message when no PDB in the catalog ships a drug-sized co-crystal ligand, instead of a silent no-recommendation state.
The cache of PDBs downloaded from RCSB now persists across deploys: structures fetched on demand survive rolling updates.

Experiment information is now generated in your language (EN/ES/PT) and cached per receptor so every reader sees the same curated paragraph.
The padding value from the experiment parameters modal now actually extends the docking search box when no co-crystal ligand is available.

Faster molecular viewer: zoom centres on the docked ligand and a loading placeholder shows progress for large receptors.
Viewer controls: switch between cartoon, stick and line representation and toggle the Van der Waals surface.
Visualise the Vina search box used for the experiment with the new 'Search box' toggle.
Default viewer representation is now stick with the search box on, so the binding pose is visible at first glance.
Admins can now browse the full history of docking experiments, with box mode, best affinity and log tail, from the Django admin.
When a receptor ships with a co-crystallized ligand the chat auto-selects it and launches the experiment without a manual PDB pick.
After the experiment a new chat bubble interprets the result as promising, moderate or weak based on affinity and pose convergence.

Guided docking: the search box centres on the co-crystallized ligand when available, with an automatic bounding-box fallback around the receptor.
Continuous integration runs the full test suite on every pull request before it can reach the main branch.
Complete Spanish and Portuguese translations across the docking chat, structure picker and experiment controls.
Reloading the page now restores the structure picker when a docking request was still pending.
More reliable experiments: robust subprocess arguments, atomic output move and visible errors when something fails.
