963 markdown files reformatted with the repository's pinned prettier so pnpm format:check covers the folded tree like every other repo file. The formatter's embedded-language pass also normalized code fences (TS semicolons, closed HTML tags in examples, lowercased CSS hex colors, one renumbered list that skipped an index). Alphanumeric token deltas vs the fold commit were audited file-by-file; all are formatter-equivalent markup normalizations plus the four sanitized skills.

Debounced watch
Usage
Similar to watch, but offering extra options debounce and maxWait which will be applied to the callback function.
import { watchDebounced } from '@vueuse/core';
watchDebounced(
source,
() => {
console.log('changed!');
},
{ debounce: 500, maxWait: 1000 },
);
It's essentially a shorthand for the following code:
import { debounceFilter, watchWithFilter } from '@vueuse/core';
watchWithFilter(
source,
() => {
console.log('changed!');
},
{
eventFilter: debounceFilter(500, { maxWait: 1000 }),
},
);
