EditorPane loads the resolved file, polls it every 2 s while visible,
reloads a clean buffer silently and shows the "Changed on disk" banner
for a dirty one, saves against the loaded hash, and intercepts closing
with unsaved edits. ViewerApp routes to the editor, the not-found list
or the choose list.
Preflight rulings carried: one reload helper that passes the truncated
flag and polled hash (P3/P14), a poll right after a save conflict so
Overwrite on save adopts the current hash (P4), a chunked base64
encoder (P5), StatusIndicator for the badge (P11), banner-only test
queries (P2), and a Range geometry stub for jsdom (P17). A save the
container user may not write is reported as read-only and keeps the
buffer.
