A high-contrast deep-ocean JupyterLab theme built from the Pelagic color palette

JupyterLab Pelagic Theme

A high-contrast, deep-ocean JupyterLab 4 theme based on the palette in colorscheme.md.

The package structure follows the same prebuilt theme-extension pattern used by carlyou/jupyterlab-nord-theme: a small TypeScript theme plugin, CSS-driven color tokens, and Python packaging that ships the built labextension.
