`SyncConnectionState` was a one-variant enum (`SignedOut`), so the
Sync page rendered "Local-only · sign-in coming soon" even after the
bearer token landed on disk and the upload thread completed. The
state machine now mirrors the actual lifecycle.
What lands:
- `SyncConnectionState` gains `SignedIn`, `AwaitingDeviceApproval`,
`SyncReady { last_synced_at_secs }`, `SyncError { message }`.
`SyncObjectState::Synced` joins the per-object enum so individual
rows can advertise "Synced" once a successful upload lands.
- `BrowserCore` stores the current `SyncConnectionState` and exposes
`set_sync_connection_state`. `sync_status` now propagates the live
state into the snapshot the UI reads.
- `ElyShell::probe_initial_sync_state` inspects
`<profile_data>/sync/bearer.token` synchronously at construction
so the first render of the sync page is honest about whether the
user is signed in.
- A `std::sync::mpsc` channel ferries upload outcomes from the
off-thread worker back to the shell; the existing 8 ms tick
drains it and stamps `core.set_sync_connection_state` with the
freshest result. The UI now shows "Signed in · awaiting first
sync", "Synced · last upload Xm ago", "Sync error · …", and the
worker-special "Signed in · waiting for device approval" when the
server returns `device_not_approved`.
Servo already publishes the live page title in every `LiveFrameReport`
but the renderer was dropping it on the floor — tabs that navigated
away from `ely://new-tab` kept showing "New Tab" forever, and there
was no favicon visible anywhere in the sidebar.
Add `BrowserCore::set_tab_title` and switch `set_tab_favicon_key` to
return `Ok(true)` only when the value actually changed; both methods
mirror the new value into the matching history entry so the History
page stays in lockstep. Derive the canonical `/favicon.ico` URL from
the loaded URL on `UrlText` and store it as the tab's `favicon_key`.
In the surface layer, every Ready frame now emits a
`WebSurfacePageMetadata` change alongside any `WebSurfaceUrlChange`,
and the controller applies title + favicon URL together. Render the
sidebar tab row's favicon via GPUI's HTTP image loader (falling
through to the URL-derived glyph for `ely://` pages, file URLs, and
hosts without a /favicon.ico endpoint).
Root cause of "settings opens new tab for every click": every
internal navigation went through `open_internal_tab → open_url →
core.open_tab(url)`, and `open_tab` unconditionally inserts a new
`BrowserTab`. So three settings sub-page clicks left four tabs in
the sidebar, which is the screenshot the user keeps sending.
Real browsers navigate the active tab in place for in-app links and
spawn new tabs only on `+ New Tab` (or Cmd-click). Wire it through:
* `BrowserTab::set_url(url)` mutates the tab's URL and bumps
`last_active_at`. Title stays put — the page renderer can refresh
it from the new URL.
* `BrowserCore::navigate_active_tab(url)` finds the active tab,
calls `set_url`, marks it Ready, records the history entry, and
bumps activity. Returns `TabNotFound` if there's no active tab.
* `ElyShell::navigate_active_tab` calls the core method and falls
back to `open_tab` if there's no active tab to navigate. The
shell's `open_internal_tab` (used by settings nav, home pills,
sidebar Settings + Profile rows, command-overlay routes, etc.)
now routes through this in-place path.
* `open_url` keeps the explicit "spawn a new tab" semantics for
`+ New Tab` and the deep-link router.
Settings, plugin marketplace, history, profile picker — every
sidebar nav now stays in one tab.

Domain ships HIDDEN_SIDEBAR_WIDTH_PX = 8 alongside the existing
collapsed/default tiers. ElyShell tracks sidebar_hover_expanded with
expand_hidden_sidebar / collapse_hidden_sidebar helpers; switching
back to a non-hidden width via the layout cards or core API resets
the flag automatically so the sidebar can never be both hidden and
expanded after a mode change.
Renderer:
- render_sidebar takes a sidebar_hidden flag and routes to a thin
8 px clickable rail (hover bg + click expands) when the active
space's width is at HIDDEN.
- While the rail is expanded, render_browser overlays a transparent
backdrop + the full default-width sidebar absolutely positioned in
the shell inset, so the main pane content never reflows.
- collapsed_sidebar_active still drives the COLLAPSED-tier compact
sidebar; the hidden tier is opted out of that path.
Appearance form:
- Layout cards section gains the design's third "Hidden on hover"
card with a 6 px sliver preview that mutates the active space to
HIDDEN_SIDEBAR_WIDTH_PX. LayoutMode now derives id/width/preview
from a small enum so adding a fourth mode would be one match arm.
The hover-expanded state never persists into the domain; once the
user switches modes or clicks the backdrop, it collapses cleanly.
Domain:
- AppearanceSettings gains translucency_pct (u8, 0..=100, default 40)
with a clamping setter and serde round-trip coverage.
- DEFAULT_TRANSLUCENCY_PCT and MAX_TRANSLUCENCY_PCT exported for the
shell.
Core:
- BrowserCore::set_translucency_pct delegates to the appearance struct;
the existing reset_appearance covers the reset path.
- Integration test covers persistence into snapshot.appearance.
Render:
- chrome::sidebar::panel_bg(snapshot) replaces the static PANEL_BG
constant, mapping the user's translucency_pct linearly into the alpha
byte 0xff..0xb3. Sidebar (expanded + compact) and main pane consume
the helper so changing the setting at runtime updates every glass
surface in lock-step.
Form:
- Translucency row in chrome::appearance_form mirrors the design's
static track + thumb visual driven by the persisted percentage, plus
three preset chips (Solid 0 / Default 40 / Glassy 75) that mutate the
setting through shell.set_translucency_pct.
Strict UX rule preserved: alpha never drops below 0xb3 so panels stay
readable without backdrop blur (which GPUI 0.2.2 doesn't expose).
The design's Slack/Linear/Gmail rows show numeric badges (12, 3) that
real apps publish in their tab title prefix — "(12) Slack | …",
"(3) Inbox — Linear", "(99+) Gmail". Add a pure parser
ely_domain::parse_title_unread_count that recognises the leading
"(N)" pattern and surfaces it through BrowserTab::unread_count(); the
sidebar launcher row renders a glass pill badge whenever the count
is non-zero, capped at "99+" for very high counts.
No domain field, no fabrication: the badge appears only when a real
website publishes its own unread count via the title. Tests cover
canonical formats, non-prefixed titles, leading whitespace, and
non-numeric / overflow inputs.
- AppearanceSettings derives Default instead of carrying a manual impl
that's identical to the derived one.
- topbar::render_lock_or_search collapses the duplicated Search arms
into a single fallback so clippy stops flagging identical blocks.
- command_overlay row helpers bundle id/title/hint/keys into a small
CommandRowContent struct so render_row, render_row_with_glyph, and
render_row_inner stay under the 7-arg threshold without losing any
call-site clarity.
Introduces a small persistent appearance contract: WallpaperTheme
(Dawn/Violet/Mint/Slate), ThemeMode (System/Light/Dark), reduce_motion.
Defaults to Dawn + System + motion-on. Field accessors and setters live
on the struct so the core can mutate without exposing internals; serde
support uses kebab-case so the on-disk form matches the design CSS
naming.
Tests cover defaults, mutation independence, and a JSON round-trip with
the kebab-case names. serde_json is added as a dev-dependency only —
the production crate does not depend on it.
