Achromatic, on purpose

Every --color-accent across the 85 templates shipped before this was checked programmatically for chroma. Not one is achromatic; this is the first. The page argues that customers get misled by reassuring language and confident presentation, so it does not lean on colour to persuade. Emphasis is type weight, rule weight and scale — and verdicts carry a word.

Frank Ruhl Libre — display serif

Literata — body serif. Two serifs on purpose: this reads as a document, not marketing. Neither appears in days 1–85.
