At 320 px with text enlarged to 200%, the sheet's nested spacing and enlarged marks leave so little label width that element names break into short fragments. Use compact horizontal spacing and stable mark dimensions on this page below 480 px, allowing names to wrap between words while keeping the text size.

Validation: 15 Python tests and manifest checks pass. Chrome checks cover 1365/682/390/320 px, both themes and 200% text, all 60 labels, no split words or document overflow, keyboard access, notice disclosure, PDF bytes and the examples/install links. The change is limited to the sheet's main class and scoped CSS.

Reviewed the two-file change at dadf1d8. No blocking findings. The media query is scoped to the sheet, keeps the text size, and leaves desktop layout unaffected. Added browser verification checks each word of every element name for line fragmentation in addition to counts, overlap and overflow. All eight viewport/theme/text-size scenarios pass, including 320 px with 200% text; corrected screenshots are readable. Existing keyboard/link/notice checks also pass, with the PDF bytes preserved. The 15 Python tests and manifest check pass. Merge remains conditional on completion of exact-head CI.
