/**
|
|
* The in-session phase presentation (owner, minimal-color round —
|
|
* monochrome now): the header chip next to the session title, and the
|
|
* dotted boundary rule the transcript draws where the session moves into a
|
|
* new phase. Phase COLOR is retired app-wide (phases only advance, so
|
|
* color-as-signal was decoration); the label text carries the phase, and
|
|
* the chip's old dot slot is repurposed for the braille spinner while a
|
|
* turn is in flight — motion is the honest state signal. Replaces the old
|
|
* inline plan-divider (artifact registry): the boundary is a MESSAGE-level
|
|
* seam, so chat.tsx renders it at the message where the phase changes, not
|
|
* inside a tool part.
|
|
*
|
|
* Quiet register (matches the old divider): hairline rules, small chips —
|
|
* never a banner. Probe never renders a divider: phases only advance, so
|
|
* probe is the start of the transcript and "Planning"/"Teaching" are the two
|
|
* visible seams.
|
|
*
|
|
* Owner, minimal-color round 2: the chip is LABEL-ONLY, deliberately — a
|
|
* working-state spinner was tried here and rejected: the pill's curve and
|
|
* the square braille cell fought for space, and the chat surface already
|
|
* shows in-flight work (thinking shimmer, the dock). The chip states the
|
|
* phase; work-state is the sidebar row's spinner.
