Pulse-Glow Text Notification

A subtle, breathing neon status line for dashboards and admin panels — the kind of 'something needs your attention' pulse that reads as alive without shouting. A soft dot and label inhale and exhale their glow together.

## JavaScript
```js
/* No JavaScript — one eased @keyframes 'breathe' shared by dot and label. */
```

How this works

A single @keyframes breathe eases the text-shadow and opacity up and down on a slow ~2.4s loop, so the glow swells and recedes like breath rather than blinking. The leading status dot runs the same timeline via a scaled box-shadow halo, keeping dot and text in phase.

Because only opacity and shadow blur animate — no layout, no color repaint of large areas — it stays cheap enough to leave running indefinitely in a live dashboard. The accent is a calm oklch green tuned for 'active/healthy'.

Make it yours

  • Retune the mood with --accent — green 'live', amber 'attention', red 'critical' all read instantly.
  • Change the tempo via the breathe duration; slower feels premium, faster feels urgent.
  • Increase the peak text-shadow blur for a stronger swell, or lower it for a whisper.
  • Drop the dot and apply the pulse to an icon-font glyph or a count badge instead.

Gotchas — read before shipping

  • Keep the pulse gentle — a dashboard full of hard blinks becomes noise and gets ignored; the breathe curve is deliberately soft.
  • This is decorative emphasis, not a substitute for a real role="status"/aria-live region if the count actually changes.
  • Animating text-shadow blur repaints; for hundreds of simultaneous pulses prefer the opacity-only technique in demo 15.
