/* base.css — the design tokens and shared chrome for every generated page.
|
|
*
|
|
* The site is deliberately typographic and light-first: a warm paper ground, a
|
|
* serif display face for headings, one ink-blue accent used only where it means
|
|
* something (links, the current page, a focused control), and colour otherwise
|
|
* reserved for code. Dark mode is the same design with the ground inverted, not
|
|
* a second theme — every colour below is a token, redefined once under
|
|
* prefers-color-scheme and nowhere else.
|
|
*
|
|
* Fonts are the platform's own. A language reference should render instantly
|
|
* and identically offline; a webfont round-trip buys nothing here. */
