/* Screen-reader-only text: present in the accessibility tree, invisible on screen. Added

   all -- a screen-reader user tabbing to one heard only "file, no file selected" with no
   indication of which of the 16 near-identical upload fields on that page it was, since
   their only visible context (the <h2> above each one) wasn't programmatically associated
   with the <input>. Standard "clip" technique -- not display:none/visibility:hidden, which
   would remove it from the accessibility tree too and defeat the purpose -- kept deliberately
   separate from the app's existing .value-na/.note-style classes so it never accidentally
   becomes visible if reused for something else. */
