19## Typecraft Guide Skill
20
21The `typography.md` reference in this project incorporates a set of tactical additions merged in from ehmo's `typecraft-guide-skill` at the author's request: dark-mode weight/tracking compensation, `font-display: optional` vs `swap`, preload-critical-weight-only guidance, variable fonts for 3+ weights, `clamp()` max-to-min ratio bound, responsive measure/container coupling, `text-wrap: balance` / `pretty`, `font-optical-sizing: auto`, ALL-CAPS tracking quantification, and the paragraph-rhythm rule (space OR indent, never both).
