Compliance Pattern
Confidential Legal Footer
A single-line confidentiality or usage notice in the footer with optional slide numbering.
Use Case
Investor, board, legal, HR, and customer decks with controlled distribution.
When to Use
Use when distribution constraints matter and every page needs the same legal reminder.
When to Avoid
Avoid in public talks, recruiting decks, or web-published materials where legal copy undermines trust.

Zone width and inset
The left, center and right zones of design.header and design.footer sit on the content inset: the slide's padding, the same left and right edge as the body, so a footer lines up with the content above it. They are three columns separated by a small gutter (2% of the slide width).
A zone with no content (no image, text, socials or date) lends its column to its neighbours. A lone zone spans the whole content width, so a long source line stays on one line; left and right together share the free centre; a center zone stays centred on the slide and only widens symmetrically. Right-to-left decks mirror the zones.
Zone text that still wraps past two lines is reported by the opf/furniture-wraps validation warning: shorten it, or move sources to a caption or the speaker notes.
Core 0.22.0 behavior.
Best Practices
Use the shortest approved legal phrase.
Keep the line muted but readable.
Do not mix multiple confidentiality labels on the same slide.
