# US-006: Announce tree unlocks

As a **player**, I want visible and actionable feedback when I unlock a species so that I notice the achievement and understand Tree Feller's safety controls.

## Acceptance criteria

- [x] Earning a species unlock displays a configurable on-screen title and subtitle naming the species.
- [x] Earning a species unlock also sends a configurable chat message that explains that sneaking prevents automatic felling and names `/treefeller undo`.
- [x] Title text, subtitle text, fade-in time, display time, fade-out time, and chat text are configurable.
- [x] Messages support the project's chosen Spigot formatting convention and a documented species placeholder.
- [x] The boss bar for the newly unlocked species is removed when its unlock announcement is shown.
- [x] An earned species produces its unlock announcement exactly once unless an administrator later resets that species and the player earns it again.
- [x] An administrative grant clearly informs an online target that access was granted but does not falsely present it as a mined-block achievement.
- [x] Invalid or cancelled breaks never generate an unlock announcement.
