atlas 39b95c2ede treefmt: apply prettier
Pure `nix fmt` output from the commit before this one — no hand edits.
203 files: 52 md, 42 tsx, 32 js, 32 css, 21 ts, 13 html, 8 json, 3 mjs.

Reproduce with `nix develop -c nix fmt` on the parent commit; the result
should be byte-identical to this tree.

None of the 13 `.prettierignore` entries appears here — verified by
intersecting the changed-file list against the ignore file, with a
control proving the intersection finds a match when one exists.

/* 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, owned by
each page's own CSS. Row taxonomy + layout contract documented in
`docs/web-ui/shape.md::Shared terminal pane` and
`docs/web-ui/terminal-rendering.md`. */

occupies one constant-width cell regardless of the glyph's rendered width
(emoji differ; some carry a variation selector), so every icon's left edge
lines up — a flat-row `🧠` and a `details` summary's `🖥️` share the column.
It's the first inline box, so the row's `text-indent: -1.4em` pulls it into
the reserved prefix slot exactly like a bare glyph; the following text then
starts at the `padding-left` (1.9em) where wrapped lines also hang. */

favour of one uniform shape, `{icon, level, summary, body,
body_format, coalesce_key}`. What used to be a dozen-odd per-kind
classes (`.turn-start`, `.tool-use`, `.tool-result.error`, `.sys`, …)
is now four: the four severities every row already carries. Structural
identity (this is a turn boundary, this is a tool call) is carried by
the row's icon (`◆`, `🔧`, `✅`, …) and summary text instead of colour —

negative text-indent). The summary's icon (when present) sits in the

`details` summary's `🖥️` lines up under a flat row's `🧠`. The
disclosure caret (`▸ / ▾`) leads the `.summary-text` (not the icon) via
`::before`, so it sits where the summary text starts rather than shoving
the icon out of the prefix column. Icon-less summaries have no `.row-glyph`,
so the caret falls back into the prefix column like the old directional
glyph. The summary text carries no `→ / ←`; the row colour (cyan =
outbound tool, muted = inbound result) carries the direction. */
