Second batch of new-layout fast-follows (master:
twentyhq/core-team-issues#2478). All changes verified live against a
running workspace.
## Settings drawer & header
- **twentyhq/core-team-issues#2489** — sidebar icons render as plain
16px icons, no background tiles.
- **twentyhq/core-team-issues#2488** — Advanced toggle spans the full
drawer width; yellow dot removed.
- **twentyhq/core-team-issues#2497** — page title stays centered in the
settings header (breadcrumb stays left).
- **twentyhq/core-team-issues#2490** — Exit Settings control aligned to
the workspace switcher (24px, matching padding/gap).
- **twentyhq/core-team-issues#2499** — 2px vertical gap restored between
collapsible drawer section items.
- **twentyhq/core-team-issues#2491** — settings drawer rhythm now
matches the main app (28px items, 2px gaps, 28px section headers).
- **twentyhq/core-team-issues#2492** — Home/Chat tab switch no longer
flickers: both tab subtrees stay mounted (a shared
`NavigationDrawerTabbedContent` toggles visibility instead of remounting
+ flashing the chat skeleton).
## Loading states
- **twentyhq/core-team-issues#2486** — metadata loading shows an empty
body (no dense skeleton rows).
- **twentyhq/core-team-issues#2487** — settings table keeps its layout
while loading, with the shimmer localized to the first row's first cell.
## Command menu & navigation
- **twentyhq/core-team-issues#2501** — navigation section header height
matches the nav item rhythm (28px).
- **twentyhq/core-team-issues#2502 (part 1)** — the page side-panel
toggle stays as the dots glyph while the command menu is open, instead
of morphing into a second close control.
## New-field flow
- **twentyhq/core-team-issues#2494** — the new-field stepper moved from
a breadcrumb dropdown into a centered secondary wizard bar (back chevron
+ Save on the configure step); breadcrumb stays clean and the object
label is the centered title.
## Descoped (substantive bugs already fixed)
- **twentyhq/core-team-issues#2500** — command-menu highlight right
gutter: the menu-item base measures full-width, so it's likely a
scrollbar gutter on the list, not the shared component. Left for a
focused follow-up.
- **twentyhq/core-team-issues#2502 part 2** — moving the command-menu
close from left to right is cosmetic (the duplicate-control bug is fixed
by part 1) and would touch the shared `SidePanelTopBar` used by
search/AI panels.
## Verification
typecheck (tsgo) + oxlint + oxfmt green for all changed files; each
change DOM-measured / screenshotted in the running app.
