Smooth Gradient Hue-Shift Border Button

The 'Most Popular' plan highlighter: the button's border and halo drift continuously through the color wheel — violet to cyan to rose and back — by animating a single registered hue number through oklch(). Because only hue moves (lightness and chroma pinned), every frame is equally vivid and the label never loses contrast.

## JavaScript
```js
/* No JavaScript — one registered number (--gbb-h) animates 0→360; every oklch() color on the button derives its hue from it via calc(). */
```

How this works

Instead of animating a giant multi-stop gradient background-position (the old way — bandy and memory-hungry), this registers @property --gbb-h { syntax:'<number>' } and animates just that number 0→360. Every color on the button derives from it: border gradient stops at oklch(0.7 0.19 calc(var(--gbb-h) * 1deg)) and a second stop offset +60°, the halo shadow, even the badge dot. One animation, total palette coherence.

The oklch choice is the modern half of the lesson: in HSL, rotating hue at fixed s/l swings wildly through perceived brightness (yellow blinds, blue goes dark). OKLCH is perceptually uniform — pin L=0.7, C=0.19 and every hue lands at the same visual weight, so the border never has a 'weak frame'. The border itself is the padding-box/border-box gradient pair (same trick as demo 07), and hover simply widens the halo and speeds the drift from 6s to 2.5s — urgency through tempo, not size.

Make it yours

  • Constrain the drift to a brand arc by animating 250→330 instead of 0→360 (alternate direction) for an on-palette shimmer.
  • The +60° second stop sets gradient 'spread' — +180° gives a two-tone opposing border.
  • Tempo: 6s rest / 2.5s hover shown; enterprise pricing pages read best at 10s+.
  • Reuse --gbb-h on the parent card's border for a matched set highlighting the whole tier.

Gotchas — read before shipping

  • syntax:'<number>' + calc(var() * 1deg) — animating a raw '<angle>' also works, but numbers let you reuse the value in non-angle contexts.
  • Without @property registration, the hue snaps once per loop instead of drifting — the same failure mode as demo 01.
  • Keep lightness ≥0.65 for dark themes; below that some hues fail 3:1 non-text contrast against near-black.

@property + oklch() gate. Fallback: a static two-color gradient border — set the custom property's initial-value and skip the animation.
