Cosmetic refinements on top of v0.5.0's content-only main pane. No
behavior change; ships as a patch bump.
## Color signal — terminal labels tinted per outcome
The transcript's [done]/[error]/[cancelled] labels were plain
foreground (Australis #a9bcc3 white), which made them slow to scan
against the surrounding assistant text. Now tinted per outcome:
- [done] → Aurora green (#16B866 / $success)
- [error] → Dawn red (#ff491a / $error)
- [cancelled] → Dawn yellow (#e1c631 / $warning)
The post-Done Rule() separator is also tinted to Australis dark-60
(#86929d) so the streamed-text → markdown-body boundary reads as
chrome, not a content artifact.
## Empty-state placeholders
Tools and Debug panes were stark-empty before any turn fired — easy
to misread as "the pane is broken." Now show placeholder lines on
mount in Sea dark-50 italic:
Tools tab: (no tool events yet — start a turn that uses tools)
Debug tab: (waiting for telemetry — start a turn)
The placeholders scroll off naturally as real events fill the panes.
## Live thinking widget self-explains
The thinking-current Static at the top of the right column used to
just display raw thinking content with no context — an operator
glancing at the screen mid-stream might not realize they were
looking at LLM chain-of-thought. Now prefixed with "thinking… " so
the widget self-identifies.
## Spacing + chrome
- Transcript / tools-log / debug-log: 1-cell horizontal padding so
content doesn't hug the column border.
- thinking-current: italic text-style on top of the dark-60 color,
so the live-preview band is visually distinct from solid-colored
log content.
- Active tab in TabbedContent: Aurora bright-cyan label + bold
text-style, so the eye lands on the currently selected pane.
- Input placeholder text: tinted to Sea dark-50 so it reads as
placeholder, not content.
## Test impact
3 new tests added (test_done_label_styled_success,
test_empty_state_placeholders_present, plus the polish hits
test_thinking_widget_truncation / test_thinking_coalesce updated for
the "thinking… " prefix). 4 existing tests that checked
`isinstance(w, str) and w.startswith("[done]")` updated to use the
_text_of helper (terminal labels are now RichText, not str).
_spy_writes helper widened to accept positional args after Textual's
internal deferred-render path started passing them positionally
post-Resize.
241/241 GREEN; ruff clean. Live smoke against personal Worldtree
confirmed: Done line renders in Aurora green #16B866 verbatim;
both placeholder lines appear in dark-50; thinking widget shows
"thinking… <content>" during a turn.
Patch bump (v0.5.0 → v0.5.1) per SemVer etiquette: purely cosmetic;
no signature change; no caller-visible behavioral shift.
