About
halloween.js is a free, zero-dependency library that adds Halloween-themed ambient effects to any website: blinking eyes, flying witches, a dropping spider, a rising tombstone, and spider webs in the screen corners. Turn it on with a single CSS class on then opt into individual effects with modifier classes. No JS call required. Works via npm or a single CDN script tag, no build step needed. Under 10 KB gzipped, MIT licensed, completely free.
Attention & discussion velocity
Not enough snapshots yet. Run the snapshot worker every 15 min to build the time-series.
Performance
Pace needs two or more snapshots. This launch has 1, so velocity and momentum read as unmeasured rather than zero.

A source that found nothing is a measurement. A source that has not run is a gap. Neither means the launch lacks the thing.
