 ### Run / build (Electron)

+cordova build electron --release --verbose   # release build

-Release build produces an AppImage (Linux) in two steps — cordova-electron bundles electron-builder v24 which ignores the Linux target, so electron-builder v26 from devDependencies is called directly:
-
-```sh
-nix-shell --run "cordova build electron --release"   # prepare platform
-nix-shell --run "node_modules/.bin/electron-builder --linux AppImage --config res/electron/build.json"
-# output: platforms/electron/build/BioLab-1.0.0.AppImage

-### Build release APK (Android)

-Signing keys are managed via agenix (`android-signing-env`). Use `--packageType=apk` to force APK output instead of AAB:

-```sh

 - External CDN dependencies: KaTeX (math rendering), Plotly (charts). Both are loaded in `index.html`; `search.js` assumes `Plotly` and `katex` are globals.
 - The `Objective` constructor detects column order from header keywords (Portuguese and English), so column order in the data table matters only when headers are absent or unrecognized.
 - `PSO` uses `Math.random` directly — `synthetic-search.mjs` patches it with a deterministic LCG for reproducible test results.
+- `solve.js` is a legacy standalone function that references globals (`RK4`, `Plotly`, `document`) and is not imported anywhere in the current codebase.
