The Brand Messaging Framework

Build a messaging framework I can use everywhere consistently.

Product/brand: [DESCRIBE]
Target audiences: [LIST IF MORE THAN ONE]
Positioning: [DESCRIBE]

Produce:
1. The core message / one-liner
2. The three supporting pillars, each with proof
3. Message variations tuned to each audience without contradicting the
   core
4. The tone and language guidelines
5. The elevator pitch, the tagline options, and the boilerplate

Make it a reference the whole team can pull from so the brand sounds like
one voice.
