/**
 * <blue-moji-picker>: a drop-in emoji picker backed by an AppView's
 * blue.moji.collection.searchItems query. Debounced search-as-you-type,
 * renders a grid of matches, and dispatches a "moji-pick" CustomEvent with
 * the chosen emoji's { uri, did, name, alt } when clicked — host apps decide
 * what to do with that (typically: insert ":alias:" into a composer).
 *
 * Attributes:
 *   api-base     AppView origin to query and load blob images from.
 *                Defaults to https://moji.blue. Must expose
 *                blue.moji.collection.searchItems and an /img/{did}/{cid}
 *                blob proxy (or override via the `img-url` property with a
 *                custom (did, cid) => string function).
 *   repo         Optional at-identifier. When set, searches substring-match
 *                within that repo's own collection (suited to "my collection"
 *                composer autocomplete). Omit for network-wide whole-word
 *                search (suited to a "discover emoji" browse surface).
 *   placeholder  Input placeholder text.
 *   limit        Max results per search (default 24).
