Keep application-owned loading chrome consistent across spreadsheet parsing phases. Hide the vendor blocking loader before render while preserving compact background progress indicators, with regression coverage for status transitions and cleanup.
Add a primary, status-aware managed download button to unsupported preview states. Shorten the spreadsheet parsing title to describe only the current phase.
