I've read the design spec and the first mockup for reference. The spec calls for a terminal-aesthetic dark theme but the mockup-1 approach was cleaner — warm white background, generous spacing, good readability.

I'll build the session view with these principles:

Each conversation turn gets 40px+ vertical padding. User messages prefixed with Q. in the accent color, assistant responses with the bot name in small caps. Tool calls collapse into colored dots — blue for reads, green for bash, purple for search, red for writes.

Updated the code block styling. They now use a warm off-white background (#F7F6F3) with slightly muted text instead of the stark dark-on-white. The border-radius is generous at 8px, and they get a comfortable 20px padding all around.

Example of the new code rendering:

const renderTurn = (turn: Turn): HTMLElement => {
  const el = document.createElement('div')
  el.className = `turn ${turn.role}`
  el.innerHTML = formatContent(turn.content)
  return el
}

The mono font drops to 13px inside code blocks — small enough to feel like an aside, large enough to remain legible. I think this keeps them feeling like marginalia rather than the main attraction.

Done. Tool calls now expand inline directly below the dot indicators. Each tool shows its colored dot, the tool name, and the primary argument (usually a file path or command). The expansion sits inside a soft grey container with a left border accent — it reads like a footnote rather than a separate UI element.

Clicking the dots again collapses it. The transition is instant — no animation, keeps the reading feel snappy.

All 142 turns rendered in under 16ms on my test data. The DOM stays light because we're not wrapping every turn in layers of containers — just semantic divs with text content.

Committed and pushed. The session view is live with the interview-style layout, warm code blocks, and inline tool call expansion.
