Story Mode

## 1.9.1

### Classic Era
- Added a hidden secret to **The Scarlet Crusade**: slaying 100 Scarlet-named foes reveals **The Scarlet Crusader**, a fourth crimson journal tab telling the story of your private war, with a live tally that keeps counting
- Added **The List**, a hunt roster of the Crusade's named figures — names are struck through in crimson as you bring them down, and the roster grows in stages as the ledger deepens
- Added quiet ledger pages at higher tallies, saving the name **Voss** for a late reveal
- Added kill notes and a banner the first time each named figure falls, plus rare banners at the ledger's deepest milestones
- Added unattributed chat whispers that foreshadow the secret before it reveals itself
- Added a persistent chat link when the secret reveals itself, so the moment can be found again
- Added a shareable ledger countersign chat link that only other revealed Scarlet Crusaders can see as a link
- Added a capstone at five thousand: the ledger stops showing its number
- Localized the kill detection for all supported client languages and gated it to NPC kills only

### Localization
- Translated all Scarlet Crusader secret text into German, Spanish, French, Brazilian Portuguese, and Russian, using each locale's official NPC names
- Reworded the in-combat error to name Story Mode instead of "this UI" across all locales

### Fixes
- Guarded story and quest chat links against being linkified twice, which could render shared links with broken formatting

### Maintenance
- Bumped addon metadata to `1.9.1`
