ThinkingStates transitions.dev shimmer text that swaps one line\n * for the next (\"Collecting context…\" → \"Reading\n * relevant files…\") — the outgoing copy blurs up as\n * the incoming one rises from below.\n * 3. ToolCallStack every tool call collapses into one stacked\n * surface — the latest call plus a count of the\n * rest; click to expand the full trace, newest first.\n * 4. SpinningReel transitions.dev digit reel: a counter that spins\n * up to the number of files scanned, with a\n * vertical-only motion blur that decays per column.\n * 5.

Swap the theme object and the whole shell changes identity.\n *\n * A conversation is a list of turns (`user` bubble · `reason` summary line ·\n * `assistant` line · `tool` call chip), so the same shell renders any script.\n * The assistant line uses the theme's `sayFont` (serif for Claude, sans\n * elsewhere) — the small tell that makes each client read as itself.\n *\n * Deps: react + tailwindcss only.
