Pricing update

Write Trestle's announcement email about a pricing change for coding sessions. Cover the facts below.

Trestle is introducing lower, more transparent pricing for coding sessions. Coding sessions let a team assign work to Trestle Agent and receive a diff ready for review.

Headline: Coding sessions now cost less.

Pricing now has two components:

• Model usage: tokens are charged at the provider's published rates, with no markup.
• Sandbox runtime: runtime is charged at $0.25 per 20-minute block.

The usage dashboard in the workspace (https://trestle-email.s3.amazonaws.com/settings) shows a breakdown of every session, including token usage and cost by model. Admins can set workspace-wide and per-user spend limits for daily, weekly, or monthly periods. When a limit is reached, additional usage pauses until the next period begins or an admin increases the limit.

These changes make it easier to start small, monitor usage, and scale adoption with confidence.
