## Say what happens

| Write | Not | Why |
| - | - | - |
| Erase reel | Submit | A key says the outcome. |
| Export September | Export | Specific beats generic. |
| Volume | Adjust the volume level | Labels are nouns, one idea each. |
| 182 ms | 182 | Numbers carry units. |
| Add the part after the @, e.g. studio@lode.example. | Invalid email! | Errors say how to fix it. |
| Preset saved to Studio A. | Success!! | Confirmations are short and factual. |

## Never

Exclamation marks, emoji, “Oops”. And no invented brands that imitate real ones in examples: the kit’s own examples use made-up names like Hearth, Quiet and Lode.

## The full law

This page is a summary in plain words. The brain holds the law itself, in `voice-and-copy.md`, written for an agent to follow. It ships with the Kit.
