[4.2.0] - 2026-03-23

Highlights

• Budget Mode: Set a budget cap and per-card ceiling when building a deck. Prices are shown throughout the build flow, over-budget cards are highlighted, and a post-build review panel lets you swap in cheaper alternatives live.
• Pickups List: New page (/decks/pickups?name=) listing affordable cards you don't own yet, sorted by theme-match priority.
• Price Charts: Donut chart and histogram showing deck spend by card role (9 categories) and cost distribution.
• Stale Price Warnings: Cards with price data older than 24 hours are flagged with a clock indicator; a banner appears when more than half the deck's prices are stale.
• Price Cache Refresh: Setup page Refresh button now downloads fresh Scryfall bulk data before rebuilding the cache.
• Multi-copy Dialogs: Conflict dialogs for Must Include and Must Exclude when using multi-copy archetypes (e.g., Hare Apparent).
• RandomService & Diagnostics: Seeded RNG service with optional diagnostics endpoint (WEB_RANDOM_DIAGNOSTICS=1).

Changed

• Build Deck button: "Create" renamed to "Build Deck" in the New Deck modal.

Fixed

• Stale price banner after refresh: Refreshing prices on the Setup page now correctly clears the stale warning.
• Multi-copy include count: Archetype card count is now correctly applied when confirmed from the conflict dialog.
