## TL;DR

The Web Storage API provides browser-side key-value storage through localStorage and sessionStorage. This repair removes quota and performance claims and keeps to the HTML Standard and MDN references.

## Core Explanation

The stable distinction is that sessionStorage is scoped to a page session, while localStorage persists for an origin beyond the current session. Both expose the Storage interface for string key-value data.
