For the IT admin: add it to everyone's mail server-side

On Microsoft 365, an admin can attach the signature to every outgoing message with an Exchange mail-flow rule. Nobody installs anything, phones are covered, and the logos switch to white in dark mode. Full details are in the README on GitHub.

1. Open the division's file in templates/exchange/. It already uses %%DisplayName%%, %%Title%%, %%MobilePhone%% and %%Email%%.
2. Exchange admin center: Mail flow → Rules → Add a rule → Apply disclaimers. Condition: sender is a member of the division's group. Action: append; paste the file's contents. Fallback: Wrap.
3. Fill in each person's Title and Mobile phone on their Microsoft 365 profile.
4. Send a test to an outside account and read it in Outlook on the web with dark mode on.
