🚀 Inspired by the Tesseract from the Marvel universe — the glowing cosmic cube that contains the Space Stone. This theme brings that energy to your editor: deep-space surfaces lit by an electric-blue glow and a bright cyan core, across five hand-tuned variants. Optimized for Operator Mono, but it looks great with any font.
- 🎨 Five variants — three dark, one light, one high-contrast
- 🪐 A cohesive cosmic palette across the editor, workbench, and syntax
- 🧪 Tested with JavaScript, TypeScript, HTML, CSS, Markdown, and Python

|---|---|---|

| Tesseract Void | Dark · OLED | Pure-black #000 surfaces; the accents glow hardest and it's easy on OLED screens |
| Tesseract Nebula | Dark | A cosmic violet/indigo mood with magenta and cyan accents |
| Tesseract Light | Light | Frost blue-white surfaces with deep-navy ink for bright rooms |
| Tesseract Singularity | High Contrast | Maximum legibility — pure black, bright accents, and crisp borders |
