Every one of syntect's bundled themes, run through meshfox's actual highlighting code (grammar + with_meshfox_scope_colors) against a sample mirroring your own canvas — meshfox marker comments, a heading, the service-flagged fence, a table. Colors and backgrounds below are the exact hex values that code produces, not approximations.
Pick one and set it in .meshfox/config.toml (local, next to the canvas) or ~/.meshfox/config.toml (global) — each card's footer shows the exact snippet.
