Installation
import { WatchlistButton } from "@/components/product/watchlist-button/watchlist-button";Overview
Shared affordance for "save to watchlist" across product surfaces (MarketCard, MarketHeader, any future market-saving context). Previously inlined per-consumer — now centralized so hover / pressed / focus treatment stays consistent everywhere it is used. Ships in two visual variants: a default standalone form, and an "overlay" form meant for placement on top of an image thumbnail.
