Priority is left-to-right, top-to-bottom: Must ships first, Won't is parked. Colour = priority; the tag = build effort. The two are independent — some Must-haves are large, some Could-haves are quick.
The prototype already covers the entire Must column and the top of Should — enough to demo the full vision with mock data. The gap to launch is the backend behind it.
Batch the four Should · Quick wins (seller storefronts, following/feed, saved-search alerts, price-guide pages) — cheap, and they deepen the community feel.
