v0.5.0

What's new since v0.4.0

• Item substitution for Skill Checks: gear can stand in for either chosen Skill's die on a Check.
• Actions tab: the 7 core Actions with a Use button that jumps to Skills with Skill 1 preset to that Action's fixed Skill.
• Notes tab: a rich-text field for freeform play notes.
• Beyond the Horizon (8+ Stress) fixes: Skill Checks now correctly collect both drawn cards regardless of outcome, and UNDERSTAND auto-succeeds with a dedicated chat card instead of rolling.
• Repair & Heal target validation: the target dropdown no longer offers Stress at 0, items already at max die, or Narrative Only items — and the ability itself now rejects an invalid target before spending any cards.
• Clue items & Clues tab: a new clue Item type (picture, title, Understood checkbox, description) with its own tab on the Scientist sheet.
• Hazard actor type: a simple image/title/description-only actor for dragging environmental hazards onto the canvas — no card-deck participation.
• Narrative Only gear no longer shows its die rating on the item sheet or Inventory row.

v0.4.0

New since v0.3.0

• Item substitution for Skill Checks: an unbroken, non-narrative-only gear item can now stand in for either chosen Skill's die on a Check, via a "Use Item Instead" dropdown per roll slot. The item takes the step-down consequence instead of the Skill when it wins — stepping down the same way, or breaking outright if it was already at d4.
• The roll panel enforces the substitution rules live: picking an item locks that slot's Skill picker, only one slot can be item-substituted at a time, and reverting to "— Skill —" re-enables both pickers.
• Internal fix: rollSkillCheck()'s resolution logic now tracks roll slots by position instead of Skill key, fixing a real bug where two slots sharing a Skill (which happens once one slot is item-substituted) could silently corrupt the roll.
• README.md now documents the Skill Check tiebreak default (an unresolved tie favors Skill 1 / the first roll slot) and the Simplified Solo known limitation.
