## [0.84.0] - 2026-09-13
### Added
- Added two bilingual Magic Point alternatives to each of the 25 cases that previously had no way to spend MP. These 1 MP and 2 MP choices channel the investigator's will to bypass a corresponding roll and take its authored success branch, while Blackwood Academy retains its existing hand-authored MP choices.
## [0.83.0] - 2026-09-13
### Added
- Added ten ambient horror effects: randomized insect shadow passes, peripheral eyes, a flowing blood-screen overlay, a cursor-following pupil, mixed left/right eye swarms, a single-eye false blink, breathing scenery, light failures, briefly reddened narrative text and impossible screen tilts. Their independent trigger chances rise with both turn count and lost SAN.
- Added a developer visual-effects test bench and automated coverage for effect rendering, cleanup and turn/SAN probability scaling.
### Changed
- Case sanity difficulty now scales authored SAN loss automatically without rewriting story files: Low remains unchanged, Medium doubles losses and High triples them. SAN recovery and HP/MP changes are unaffected.
- Periodic SAN drain now follows case sanity difficulty: every 10 turns on Low, every 8 turns on Medium and every 6 turns on High. Its existing escalation remains one additional SAN after every three triggers, capped at SAN -4 per trigger.
- Removed the Forgiveness/tolerance difficulty rating from location data, the Locations interface and the case-difficulty estimator; cases now show only Life threat and Sanity pressure.
