Library input crosses an overload boundary into either immediate execution or a curried function carrying optional lazy metadata. Pipeline transformations keep their working state within the invocation and produce arrays or single values without a persistence service. Documentation follows a separate path from TypeScript reflections through validated Astro records into rendered HTML. Browser theme preferences form the concrete persistent user-state path inspected here.
- purry computes fn.length minus args.length: zero invokes fn immediately, one creates a data-last wrapper, and any other difference throws Wrong number of arguments.
- Direct map and filter calls delegate to native array methods with the original input array available to callbacks; their data-last functions additionally carry lazy and lazyArgs metadata when constructed through purry.
- pipe instantiates evaluators once per invocation, groups adjacent lazy steps for iterable outputs, accumulates their results, and unwraps the first accumulated item when the terminal evaluator is marked single.
- Each lazy step records its incoming values before calling its evaluator; hasNext controls forwarding, hasMany recursively processes expanded values, and done propagates early termination to the outer iterable loop.
- groupBy invokes its callback with item, index, and full input, skips undefined keys, accumulates nonempty arrays in a null-prototype object, then restores Object.prototype before returning.
- The functions collection resolves the installed workspace package to a real path and passes its tsconfig and src/index.ts to TypeDoc; function reflections are parsed into named, digested Astro store entries.
- getFunctions groups stored functions by the first signature's category tag; cards deduplicate signatures by @signature and place data-last variants last, while description Markdown passes through marked and DOMPurify before HTML insertion.
- Theme selection changes the document's dark class and DocSearch data-theme attribute; explicit light/dark choices persist under localStorage key theme, while system selection removes that entry and consults matchMedia.
