/**
 * The CSS selector that finds a store's account link in the header.
 *
 * Built from `context.routes.accountUrl` rather than a literal `/account`,
 * because that value is whatever the store actually renders: a locale prefix
 * (`/en-gb/account`), the `shopify.com/<id>/account` URL new customer accounts
 * use, or a custom domain that need not end in `/account` at all.
 *
 * Four rules per route, not an `ends with` match:
 *   - exact, so `/account/logout` and `/account/register` are left alone
 *   - followed by `?`, because account URLs carry search params (a `return_url`
 *     on new customer accounts, most often)
 * and the same pair for the login route, since themes point the header icon at
 * the login one while the customer is signed out.
 *
 * Scoped to `<header>`: a placement mounts on *every* match, so unscoped this
 * would also claim the footer's "My account" and hang a saved-count badge on a
 * plain text link.
