When :href is provided, the button renders as <a> instead of <button>,
enabling navigation links with full button styling.
New :link variant renders as a minimal text link (underlined, accent
color, no background/padding) — works as both <button> and <a>.
CSS includes reset styles for a.btn (removes default link decoration)
and preserves underline for a.btn-link.
Add :scales config to tokens.edn with two generated scales:
- Size (linear): --size-1 through --size-16, base 0.25rem × N
- Font (geometric): --font-xs through --font-3xl, ratio 1.25
gen.clj computes values and emits them into :root only (not dark
theme blocks). button.css now uses scale vars instead of raw rem.
Change base or ratio in tokens.edn to recompute the entire scale.
- Rename CSS classes from BEM double-dash (btn--primary) to flat
utility-style single-dash (btn-primary)
- Move button CSS from inline Clojure string in gen.clj to
src/ui/button.css next to button.cljc
- gen.clj now auto-collects all src/ui/*.css files via babashka.fs glob
- Replace clojure.java.io with babashka.fs throughout gen.clj
- Update AGENTS.md to reflect new conventions
