static-design-system — head.html
Shared contents of . The consuming site wraps it:
{% include ds/head.html %} ...site-specific tags...
Expects site.title, site.description, site.author, site.url.
Loads the fonts, the shared CSS (/assets/ds.css), then the site's color
overrides (/assets/colors.css) — order matters — and inlines the pre-paint
theme script to avoid a flash.
