v0.4.0

Craps Sim 0.4.0 rebuilds the interface as a four-mode instrument: Design (bet rail with per-bet edge ticks, progression cards, chip toggles, house rules), Findings (Endurance, Horizon, and Stake over one streaming run), Explorer (the strip of 528 combos with an honest leaderboard), and Replay (roll-by-roll session theater). Runs stream into the charts as they simulate, with instant cancellation and fully interactive partial results.

Highlights:

• The Anchor — swap any of the twelve progressions on the Horizon histogram and watch the distribution morph, re-simulated on identical dice; the per-dollar edge marker stays pinned while the expected-loss pin drifts.
• The Duel — paired comparison of two strategies under common random numbers: identical dice, a same-dice replayed session, a y = x scatter, a paired-difference histogram with a tie band, and a paired decile ladder.
• Session Replay — any percentile, bar, or dot opens the exact re-simulated session inside the population's percentile envelope, above a roll-by-roll dice strip with bet resolutions to the cent.
• The Scenario Sentence — the whole configuration as one line of prose; copying it is the save format, pasting one reconstructs the setup.
• Chart interaction — brush to zoom, ⌘-scroll zoom, ⇧-scroll pan (clamped to the data), and up to three pinned references that print their values, the Δ between the last two, and survive into 2× PNG exports with provenance baked in.
• Closed-form house edge everywhere — per-bet ticks and a blended edge strip in Design, a fixed EDGE column in the Explorer, and the edge in the status baseline.
• Dark and light themes, an explicit user-visible seed, and a deterministic engine with pinned outcome checksums.

The macOS build is a signed, notarized DMG. See CHANGELOG.md for the complete list.
