An Obsidian theme for deep-focus writing and reading.
Named for the soft, persistent glow of phosphorescent ink — text that lingers in the mind after the page goes dark.
- Spectral arc headings — warm amber (H1) through cool sage (H6), mirroring natural reading energy
- Tuned for long-form reading — 18px base, 1.72 line-height, ~68ch measure, perfect fourth type scale
- Dark and light modes — both built around the same warm-to-cool palette
- 20+ custom checkboxes — icons for tasks like
[!]important,[?]question,[/]in-progress,[I]idea,[b]bookmark,[P]PR open,[M]PR merged, and more - Pure CSS — no build tools, no dependencies, just
