* feat(chat): ghost-style tool containers
Remove borders and card styling from tool call UI. ToolFallback
uses minimal padding with indented content. ToolGroup defaults
to ghost variant with subtle background for multi-tool grouping.
* feat(chat): compact web search source pills
Switch sources from vertical full-width badges to horizontal
wrapping pills with smaller icons.
* feat(chat): left-accent code and terminal tool UI
Replace bordered card layout with a left border accent for
Python and Terminal tool output. Add timer cleanup on unmount
for the copy button in both components.
* feat(chat): inline latex and clickable links
Enable single-dollar $...$ math rendering via createMathPlugin.
Add styled link component with target=_blank for external links.
* fix(chat): inline generating indicator, static tailwind classes, misc fixes
Move generating indicator from viewport footer into assistant
message using AnimatedShinyText shimmer. Only shows when message
content is empty, hides once tool calls or text appear.
Use static size class map in SourceIcon for Tailwind v4 compat.
Use unique keys for web search sources. Remove px-3 from ghost
tool group variant.
* fix(chat): only show generating indicator while message is running
Hide the shimmer when message is cancelled or errored with no
content, preventing stale loading UI on empty completed messages.
* fix: escape currency dollar signs in LaTeX math rendering and fix TS build error
- Add preprocessLaTeX() in lib/latex.ts to escape currency patterns ($5, $1,000, $5.99, $100K)
before they reach the math parser, preventing false positives when singleDollarTextMath is enabled.
Code blocks and already-escaped dollars are left untouched.
- Use preprocessLaTeX via useMemo in markdown-text.tsx so Streamdown receives clean input.
- Fix TS18048 in thread.tsx: message.status?.type (optional chaining) since status can be undefined.
