+The editor saves the current source even when it has an error. A recoverable error ignores only the invalid declaration,
+value, selector, or rule; valid parts still appear in preview and PDF export. A fatal version or resource-limit error
+ignores the whole stylesheet and renders the resume with its base styles until you fix the source.
 
 If a rule does not work:
 
 1. Read the status below the editor. Errors include a line and column number when available.
 2. Check the selector's spelling, attribute value, placement, and template guard. A **selector matches nothing**
    warning usually means the resume does not contain that semantic node.
