A deep-sea file & folder icon theme for VS Code & Cursor. Inspired by IntelliJ Atom Material Icons. Recoloured with the Lusitania palette.

Pairs with the Lusitania colour theme so the editor and the explorer share one visual identity. Every icon is a unique silhouette — never a generic letter on a coloured square — and the long tail of file types gets a clean folded-document glyph rather than a placeholder.

Security

This extension is purely declarative and ships only static assets:

package.json has no main, activationEvents, scripts, extensionDependencies or extensionPack — VS Code never executes code from this package.
The only contribution is iconThemes (a JSON mapping + 302 SVGs).
SVGs contain no <script>, <foreignObject>, <iframe>, xlink:href, href="http…", data: URIs, event handlers or CDATA sections.
No network calls, no telemetry, no file-system access.

Verify with one grep:

grep -rEi '<script|foreignObject|xlink:href|javascript:|on(load|click|error)=' icons/

Build

Icons and the mapping are generated by build.py; preview images by build_previews.py. Both use Python 3 standard library and qlmanage (macOS) for SVG → PNG — no external dependencies.

python3 build.py             # rewrites icons/*.svg and lusitania-icons-theme.json
python3 build_previews.py    # rewrites previews/*.svg and previews/*.png
