  style(tui): UI polish pass (v0.5.1)

  vh released this 2026-05-24 15:06:10 -07:00 | 259 commits to main since this release

  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… " during a turn.

  Patch bump (v0.5.0 → v0.5.1) per SemVer etiquette: purely cosmetic;
  no signature change; no caller-visible behavioral shift.
