+/* Shared terminal pane: a scroll-sticky log of rows + a "↓ N new" pill.
+   Pages wrap their stream container in `.terminal-wrap` and give the log
+   itself the `.live` class; renderer JS appends `.row` (flat line) or
+   `details.row` (collapsible body) elements. Row-kind classes
+   (`.turn-start`, `.tool-use`, `.thinking`, etc.) carry the per-event
+   colour; pages that don't emit a given kind simply never produce that
+   class — the unused rule sits in the bundle harmlessly.
+
+   `.terminal-wrap` provides the crust-on-black phosphor chrome that makes
+   the agent page feel like a terminal. Pages can opt in by wrapping a
+   block in this class; or skip it and the rows still render with their
+   class colours, just without the frame.
+
+   No `.term-input` here — composers are a separate concern (see
+   hive-fr0nt::COMPOSER_CSS / COMPOSER_JS once introduced). */
