One of four divergent candidates for the bold consumer theme family (committed saturated color at 30-60% surface coverage, strong display type). Includes the post-diverge fixes: heading color:inherit so brand slabs keep their foreground pairing, plus per-theme refinements. Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>

/*
|
||
* Klein — ultramarine drench.
|
||
*
|
||
* Yves Klein blue as the identity. The background field ITSELF is a committed,
|
||
* saturated deep ultramarine — not a tint, not an accent, the world you stand
|
||
* in — carrying near-white ink. Cards are clean near-white panels floating on
|
||
* the blue, with dark ink on top. This inverts the usual light-theme logic:
|
||
* :root (light mode) IS the drenched blue world; the blue carries 30–60% of
|
||
* every surface by construction.
|
||
*
|
||
* The counterpoint is a warm amber-orange (hue ~60) spent on the primary
|
||
* action, focus, selection, and the user chat bubble — the one hot signal that
|
||
* pops off the ultramarine. Secondary and muted stay inside the blue family
|
||
* (deeper stripes of the same hue); the sidebar is a deeper band of
|
||
* ultramarine. Borders are dark hairlines because borders live on the white
|
||
* cards and inputs; the sidebar gets its own white-alpha hairline token.
|
||
*
|
||
* Dark mode is ultramarine at midnight: the field deepens, cards become deep
|
||
* blue panels stepping LIGHTER off the field, ink stays near-white — the theme
|
||
* is unmistakably blue in both modes.
|
||
*
|
||
* Type is the art-poster voice: Syne (700+) for headings, Inter for body,
|
||
* JetBrains Mono for code. Consumer register — generous 1rem radius, confident
|
||
* motion (150/300/450/600ms) with real gentle springs, deep blue-black shadows
|
||
* (a drenched field casts blue shadow, never gray).
|
||
*
|
||
* Token contract matches lib-theme-caffe-florian/theme.css (Crema v1).
|
||

||
|
||
/*
|
||
* Fonts: consuming apps load Syne + Inter + JetBrains Mono at the top of their

|
||
* the URL in a comment for a build script to lift — breaks PostCSS's ordering
|
