/* "Kick Font" by NachoZombiezz - the brand display face, SIL OFL 1.1. The licence and the archive
   readme ship beside it at ui/assets/fonts/kick/ because FontStruct's terms require the font to be
   redistributed with its accompanying files.
   Declared as `KickInput`, a private name, so it can only ever be reached by the one rule below -
   nothing can pull it into --font by accident.
   It is a FontStruct modular face: 106 glyphs, complete for a-z A-Z 0-9 _ - and punctuation, which
   is everything a Kick username needs, but it has no other coverage - hence the system stack behind
   it so anything unusual still renders.
   ascent/descent-override pin its 1.2500em line box to Segoe UI's 1.3301em, so swapping the font in
   moves nothing vertically. Its x-height is 0.583em against Segoe's 0.500em, so it reads noticeably
   larger at the same px - that is the face, not a bug. */

   BRAND: TVB (Twitch)
   ----------------------------------------------------------------------------
   kvb.gg and tvb.gg serve the SAME stylesheet and the SAME JS bundle; the only
   difference is the `data-brand` attribute each site's PHP puts on <body>.

   The whole accent system is derived from a single hue via oklch(), so the
   entire ramp - buttons, glows, focus rings, the four background gradients -
   follows from changing ONE number. 140 is Kick green (#53FC18); 295 is Twitch
   purple (#9146FF). Nothing else needs a per-brand rule.

   MUST be :root (the <html> element), NOT <body>. --accent and the rest of the
   ramp are DECLARED on :root as oklch(... var(--accent-h)); custom properties are
   substituted at the element where they are declared, so redefining --accent-h on a
   descendant like <body> leaves the derived ramp resolved at :root's value and the
   page stays green. Setting it on <html> is what actually re-derives the ramp.

   Scoped to [data-brand="tvb"], so KVB is untouched: it never sets the attribute.

:root[data-brand="tvb"] {
  --accent-h: 295;

  /* The hue alone is NOT enough. The ramp above is tuned to Kick green #53FC18, which is an
     unusually LIGHT colour (L=0.869). Rotating only the hue keeps that lightness, and purple at
     L=0.869 is a pastel lilac, nothing like Twitch's #9146FF. So the ramp is re-derived here at
     the lightness purple actually needs.

     --accent-ink is the critical one: it is the text colour used ON an accent-filled button.
     KVB sets it DARK (L=0.22) because bright green needs dark text. Twitch purple is a DARK
     colour, so inheriting that would put near-black text on a dark purple button - illegible.
     It is flipped to near-white here. */
  --accent:      oklch(0.62 0.24 var(--accent-h));   /* ~#9146FF, Twitch purple */
  --accent-soft: oklch(0.72 0.19 var(--accent-h));
  --accent-deep: oklch(0.50 0.22 var(--accent-h));
  --accent-ink:  oklch(0.97 0.02 var(--accent-h));   /* text ON accent - light, not dark */
  --accent-glow: oklch(0.62 0.24 var(--accent-h) / 0.45);
}

/* The clay primary button does NOT derive its colours - it bakes them as literal greens
   (#6BFF3C / #3FCB0E / #1F7A00 and a dark-green inner shadow), so the hue override above cannot
   reach it. On TVB that left every primary button Kick-green while the rest of the page went
   purple. Re-derived here from --accent-h so it tracks whatever the brand hue is.
   The three stops mirror the original's shape: a lighter top, the accent in the middle, a darker
   bottom, plus the solid 6px "edge" underneath that gives the button its clay depth. */
