Sheet
A panel that slides in from an edge.
Left out of Brand expressive Phones first: drawer is the bottom panel for phones and already holds the menu, and dialog holds the waitlist form. Use instead: Drawer, Dialog

Instead:
How Brand expressive uses it
A menu or dialog
Use elevation.overlay and a dimmed page
Not No shadow
Strong depth shows a menu or dialog sits above vivid sections. Without a shadow it blends into the color blocks.
Words
- Headlines are short and bold. Three to six words.
- Verbs that move: Join, Try, Go.
- Playful in headlines, plain in errors.
- Use: Join, Drop, Go, Love. Avoid: Synergy, Leverage, Kindly.
The labels components use, from the voice tokens:
content.action.commit: Gocontent.action.cancel: Not nowcontent.action.destroy: Removecontent.action.retry: Try againcontent.action.empty-action: Explore the drop
See Voice and tone for the whole voice.

Use it in code
npx open-ds add sheet
The component reads only component keys and semantic tokens, so it follows the brand and mode on <html>.
Tokens it reads
Sheet reads 19 tokens of its own, each an alias of a semantic token. Each row is one part: its own token, the semantic it aliases, and the value it ends at. Change a semantic and every component that reads it follows; override one of Sheet's tokens to change Sheet alone.
Changes with theme
Brand expressive decides what changes when you switch theme. Here a switch changes colors only, so the marked rows differ between light and dark; everything else holds steady.
