7. Subclass Flavor Prompts

Each subclass selection triggers a TwinBee narration line and a one-line flavor acknowledgment in the player's character sheet. Examples:

• Champion: "You've chosen the old way. No tricks, no systems. Just you, and the blade, and the next hit. TwinBee approves of this directness."
• Arcane Trickster: "Magic in the hands of a Rogue. TwinBee considers this the universe's way of apologizing for giving you low HP."
• Necromancer: "Undeath as a tool rather than a state. TwinBee has opinions about this. TwinBee is keeping them to itself."
• Beast Master: "You and your pet, all the way down. TwinBee finds this genuinely moving and declines to be embarrassed about that."
• Gloom Stalker: "You were already good in the dark. Now you're better. TwinBee notes: the Underdark is waiting."
