* fix(frontend): cap deeply nested list indentation to prevent render crash
Deeply nested lists make marked's recursive list tokenizer overflow the
call stack during Streamdown's lexing useMemo, throwing an uncaught
"RangeError: Maximum call stack size exceeded" that replaces the chat
route with an error page (issue #3393); on larger stacks the same input
exhausts the heap, which the render error boundary cannot catch.
Mirror the existing capBlockquoteNesting guard with capListNesting, which
clamps leading whitespace to 200 columns (~100 nesting levels) only when
pathologically deep indentation is present, leaving normal content and
fenced code untouched. Wire both through capMarkdownNesting.
* fix(frontend): satisfy prettier format check in preprocess test
* fix(frontend): exempt indented code from list-indent cap (PR #3570 review)
* fix(frontend): keep capping all deep indentation outside fenced code
Revert the indented-code exemption from the PR #3570 review nit. Taken
literally the suggested guard (insideFence || INDENTED_CODE_RE.test(line))
no-ops capListNesting, because INDENTED_CODE_RE matches every line with
4+ leading spaces — i.e. exactly the deep-indent lines the cap targets.
A context-aware exemption (only treat 4+-space lines as code after a
blank line) instead reopens the crash: blank-separated deeply nested list
items get exempted and still blow up marked (verified: OOM at depth ~1.5k).
Unlike blockquotes (markers take <=3 leading spaces, so deep-quote lines
never look like indented code), list vs. indented-code indentation is
ambiguous line-by-line, so any exemption is exploitable. Keep capping all
deep indentation outside fenced code; the only cost is mild corruption of
a >200-column indented-code line, which never occurs in real content and
is strictly preferable to a render crash. Add a regression test locking
the blank-line case.
* fix(frontend): render user messages as plain text and cap blockquote nesting
User messages are typed or pasted plain text, not authored Markdown, but
they were rendered through the full Streamdown pipeline. Pasted source
files got fragmented (indented chunks become code blocks, paragraphs
collapse and lose indentation), "$...$" spans were KaTeX-ified, and a
message with thousands of nested ">" markers overflowed the call stack
in marked's recursive blockquote lexer, permanently crashing the thread
on every load.
Render human message content verbatim with pre-wrap instead, and cap
blockquote nesting at 100 levels at the Streamdown chokepoint so model
output cannot trigger the same recursion either.
Closes#3500
* fix(frontend): absorb marked lexer crashes with a render fallback boundary
Review found two gaps in the nesting cap: marked's list and blockquote
tokenizers are mutually recursive, so a list marker in front of the
quote chain ("- > > > ...") bypassed the blockquote-only regex and
still overflowed the stack; and the line-based rewrite was fence-blind,
silently truncating literal ">" runs inside code blocks.
Add an error boundary around Streamdown that renders the raw content as
plain pre-wrap text when rendering throws (retrying on the next content
change), keep the cap as a fast path for the dominant pure-">" case,
and make it skip fenced and indented code lines.
* fix(frontend): make Suggestion button opaque in dark mode
The outline Button variant applies dark:bg-input/30, leaving Suggestion
pills ~70% transparent in dark mode. Scrolled chat content bled through
the buttons, making suggestion text unreadable. Override with
dark:bg-background so it matches the opaque light-mode appearance.

When citation data is not available, use the markdown link text
(children) as display text instead of just the domain. This ensures
that links like [OpenJudge](github.com/...) show 'OpenJudge' instead
of just 'github.com'.
