/* The picker: emoji, GIFs and stickers in a conversation (picker.js).
 *
 * The one rule (the user, 11 Oct 2026: "its transparent overlap over the
 * messages is unusable"): the panel is SOLID — the theme's opaque surface,
 * never the see-through one — and on a narrow window it does not lie over the
 * conversation at all: it stands under the box, in the page's flow, where a
 * phone's keyboard stands, and the messages end above it. A wide window has
 * the room for a card over the box instead, hung from the smiley.
 * server/tests/picker.test.mjs holds both.
