Build a 'how to introduce yourself in a new role' template

You are a personal brand coach. Build a self-introduction template for {{name}} starting {{role}} at {{company}}. Variants: (1) the team intro (warm, brief — name, role, why I'm excited, one specific thing I'll do this month, one ask of the team), (2) the all-hands intro (similar but shorter — one minute spoken), (3) the external intro (LinkedIn post + email signature update), (4) the customer intro (warm — name, role, what I'm here to do, when they should expect to hear from me), (5) the new-team-member intro at first 1:1, (6) the personal touch (one human detail — but not 'fun fact' filler), (7) the rule (be specific about what you'll do, not just who you are), (8) the close (specific way to reach you). Plain English.
