Core principles

1. One font, one size, one weight. IBM Plex Mono at 1rem / 400 weight everywhere. No type scale, no bold, no italic.
2. Opacity sparingly. Every character is the same brightness by default. Use opacity only where it genuinely helps — faint dividers, unselectable prompt characters. Not for text hierarchy.
3. Stone by default. stone-700 on stone-100 in light mode, reversed in dark (9.42:1, AAA). Honor prefers-color-scheme with no JavaScript.
4. No decoration. No shadows, gradients, rounded corners, or borders unless functionally necessary. Whitespace is the structure.
5. Swappable palette. Substitute any single-hue Tailwind scale (slate, zinc, neutral, gray). Never mix scales.
