+Tests for Evolution Tier Completion Notification embeds.
+
+These tests verify that:
+1. Tier-up embeds are correctly formatted for tiers 1-3 (title, description, color).
+2. Tier 4 (Fully Evolved) embeds include the special title, description, and note field.
+3. Multiple tier-up events each produce a separate embed.
+4. An empty tier-up list results in no channel sends.
+
+The channel interaction is mocked because we are testing the embed content, not Discord
+network I/O. Notification failure must never affect game flow, so the non-fatal path
+is also exercised.
