Workspace settings
These apply to every project in the workspace. Nothing changes until you save, and a discard puts every row back.
A settings page with the heading, save and discard buttons held in a sticky left column and three collapsible groups of rows on the right: text inputs, selects, a segmented choice, switches, a masked API key with copy, a warning note and a destructive action. Rows are data, edits live in local state, and a counter beside the save button shows how many are unsaved.
