LLMs routinely emit JSON/YAML *fragments* in fenced blocks — a bare
`"key": "value"` line, snippets with `...`, trailing commas — which
legitimately fail JSON.parse. initTreeViews() stamped an unstyled
`<div class="tree-parse-note">parse failed</div>` below such blocks,
producing bare white text under an otherwise-clean code box.
The note was incidental, not designed: it was bolted onto the YAML
lazy-load commit (29a31a6e), has no CSS, no behavior test, and originally
even fired on *valid* YAML before the CDN script finished loading (later
fixed). The block still renders as syntax-highlighted raw, so the note
added only noise.
Remove the note insertion; fall through silently to raw view. The per-block
Raw/Tree toggle, YAML lazy-load, and the #484 default-view config are all
unchanged. The `parse_failed_note` i18n key is intentionally retained (kept
green by test_chinese_locale.py) to avoid touching all 13 locales.
Verification: ./scripts/test.sh tests/test_issue484_json_tree_viewer.py
tests/test_chinese_locale.py — 29 passed.
