/**
 * The write-a-review form: a login gate, stars, body, identity row, actions.
 *
 * One markup, two dialogs. The reviews panel on a mint page opens it directly; the
 * review-by-URL dialog on an index page opens it as its second step, once the reader's
 * pasted address has been indexed. Its behaviour lives in `lib/write-review.ts`, and
 * every hook below (`data-write-*`) is what that module binds to.
 *
 * Three states, only one of which is ever on screen:
 *
 *   1. **Gate.** No session and no NIP-07 extension: there is nothing to sign with, so
 *      the dialog asks for a login before it asks for anything else. Writing a review
 *      into a form that cannot publish it is the one outcome worth designing away.
 *   2. **Stars.** The rating is the whole first step. It is the one thing every review
 *      must carry, it takes one tap, and it is what the rest of the form is *for*.
 *   3. **The rest.** Body, identity and publish, revealed once a rating is chosen.
 *
 * Nothing here knows which ecosystem is being reviewed. The heading is a slot because
 * the two dialogs have genuinely different heads — one names the mint, the other has a
 * step back to the address field — and the lede and placeholder are props for the same
 * reason: "how did minting and melting work out" means nothing about a federation.

   * whole reason they exist; nothing styles by id.
