Replicant Runner Theme

A green-and-red cyberpunk theme for VS Code, in dark and light, tuned so you can read it for eight hours straight.

This is a fork, not an original theme. All the colour work is punk-runner by TheEdgesofBen — originally an Atom theme, later ported to VS Code by the same author. Replicant Runner only retunes it for contrast. If you like how it looks, that's their eye, not mine. See NOTICE.md.

What the retune changes

Contrast raised to WCAG AA — foregrounds lifted or dimmed against the editor background so no token pair sits below 4.5:1.
State colours de-collided — selection, find match, word highlight, and hover highlight no longer share a hue, so overlapping states stay readable.
Semantic highlighting enabled, with explicit colours for enumMember, variable.constant, and variable.defaultLibrary.
Light variant — the aqua, coral and violet trio on warm cream paper, with amber for numbers and constants and cyan for regex and escapes. Every token sits between 4.5:1 and 11.5:1 against the editor background, and the state washes keep their hue and border logic.

403 workbench colours, 258 token rules, 3 semantic token rules, two variants.
