# Slack Notification Ad editing contract

## Surface ownership

This template depicts Slack notifications on an iOS lock screen. Slack and iOS own the notification and device chrome. The supplied website may appear only in declared notification copy and the final payoff identity.

## Editable slots

Only defaults declared in `data-composition-variables` are editable:

- The eleven request titles and messages
- The final payoff title, message, and logo

Keep replacement copy within 20% of the original length. The payoff logo must remain legible in the existing icon tile.

## Protected

Preserve the Slack mark on request notifications, iOS status/date/clock labels, wallpaper, notification chrome, fonts, palette, stacking geometry, scene structure, duration, timing, easing, and arrival cadence.

Website colors and typography must never be applied to the Slack or iOS shell.
