/* =====================================================================
* tyrell-brand.css — OKLCH-based brand layer for Tyrell Components
* =====================================================================
*
* Opt-in. Load AFTER `tyrell.css`. Override a few variables to rebrand.
*
*
*
*
* :root {
* --ty-brand-hue: 200; // teal. Try 260 indigo, 30 orange, 145 emerald.
* --ty-brand-chroma: 0.13;
* }
*
* Primary, secondary, neutral, surfaces, inputs, solid buttons all retint.
* Success / danger / warning stay semantic (green / red / amber) — override
* their *-hue/*-chroma seeds if you want them to follow the brand too.
*
* Three layers of knobs you can override at :root (or html.dark for
* per-mode tuning):
*
* 1. SEEDS — per-flavor hue + chroma.
* --ty-brand-hue, --ty-brand-chroma
* --ty-secondary-hue, --ty-secondary-chroma (default: brand + 60°)
* --ty-success-hue, --ty-success-chroma (default: 145°)
* --ty-danger-hue, --ty-danger-chroma (default: 25°)
* --ty-warning-hue, --ty-warning-chroma (default: 75°)
* --ty-neutral-hue, --ty-neutral-chroma (default: brand-hue, 0.005)
*
* 2. L-CURVE — lightness stops shared by every flavor.
* --ty-l-strong, --ty-l-bold, --ty-l-base, --ty-l-soft, --ty-l-faint
* --ty-l-bg-base, --ty-l-bg-bold, --ty-l-bg-soft
* Defaults in `:root` are tuned for light mode (lower L = more
* emphasis). The `html.dark` block redefines them with inverted
* values. Override either block to compress / expand the ladder.
*
* 3. SATURATION CURVE — chroma multipliers per shade.
* --ty-c-strong-mult, --ty-c-bold-mult, --ty-c-base-mult,
* --ty-c-soft-mult, --ty-c-faint-mult
* --ty-c-bg-base-mult, --ty-c-bg-bold-mult, --ty-c-bg-soft-mult
* Multiplied against the flavor chroma seed. Bump --ty-c-bold-mult
* to 1.2 to make `+`-emphasis text more saturated; drop
* --ty-c-faint-mult to 0.2 for whisper-quiet placeholders.
*
* Browser support: OKLCH is in every evergreen browser since mid-2023.
