The Design Files pane used to sit on an empty state until a run finished
and the first artifact dropped in. Everything the run was doing happened
somewhere the user could not see, and the wait carried no signal that
anything was happening at all.
It now watches the shallowest index.html the run has produced (or the
most recently written HTML file) and renders it live beside a feed of the
steps behind it, with a toggle between the step feed and the full
preview. A new cross-runtime contract, preview-build-focus, lets the
sandboxed preview frame answer "where in this page are you writing right
now" — either by a literal string the agent just wrote or by naming one
of the page's own top-level sections — so the host can walk a cursor down
the page as it is written instead of jumping to wherever the last run of
text happens to land. The frame has no allow-same-origin, so it posts to
'*' and the host identifies it by event.source.
latest-user-prompt goes away with the empty state that echoed it: the
pane now names what the run is doing, which is the more useful of the
two, and keeping both meant recomputing a prompt string on every streamed
token for a line nobody read.

Reworks the entry experience end to end — the Home hero and its composer, the
nav rail, the workspace tab bar, the recent-projects strip, the community
gallery and the message center — and adds the per-project run status the rail
and the strip now render.
Home / entry
- Hero headline cycles a noun out of `homeHero.titleWords` (RotatingTitleWord);
locales whose `homeHero.title` carries no `{word}` stay a plain sentence.
- The composer is now one component in two shapes: `page` (Home's full column)
and `dock` (the bar alone, used by the community view), sharing @mentions,
staged files, the working-directory row and submit.
- ComposerModePicker is gone; ComposerPlusMenu absorbs what it offered.
- Entry layout, nav rail (with RailRecentRow), workspace tabs and the recent
projects strip are restyled together against one set of measurements.
Run status
- New `projectRunStatus` state, `useProjectRunStatuses`, `run-progress` and
`latest-user-prompt` runtime helpers, and `ProjectRunStatusIcon`.
- `ChatRunsResponse` gains `awaitingInputProjectIds`: a run that asked a
question reads `succeeded` while the project is still blocked, so a caller
rendering per-project status needs the set to avoid showing such a project
as finished. Optional — absent means unknown, not none.
Community / message center / design files
- Community gallery gets its own empty state, and the message center gets
archive plus a reworked card.
- Design files panel gets a dedicated empty state component.
Daemon / desktop / sidecar
- Project create bounds its read-only preparation work (15s) so a stalled
local catalogue scan cannot strand the web on an optimistic route or leave a
half-initialized project behind.
- The startup splash runs the same pixel-scan wordmark as the Home hero,
ported to raw WebGL because the splash renders before the sidecar boots
(replaces the splash video).
- Sidecar proxy tracks the in-flight request/response so a keepalive replay
tears down the previous attempt instead of leaking it.
New visuals: SiriOrb, MarqueeLabel, SpaceBackground, the composer beam and the
chat-cards-next surface.
No placeholder data ships with this: the community card byline (author name and
view/remix counts) and the message center's temporary cover image are removed,
so the card footer shows the title only and the media slot renders only when a
message payload actually carries `imageUrl`.
