 **One 26px target, opens the picker — never cycles, never selects**: clicking anywhere in the zone opens the combined Label picker anchored at the row's bottom-left (an `absolute left-0 top-full z-50` wrapper; the row root stays overflow-free so the `top-full` popover is not clipped even on a selected+double row). The click `stopPropagation`s so it does not select the row, and coexists with drag-reorder. Cursor is `pointer` (menu-opener semantics). The zone is enabled on non-ghost rows wired with both the color and marker write seams plus a `server` (`labelZoneEnabled`).
 
-**Zone geometry**: an absolute `z-20` sibling positioned `left-0` spanning `LABEL_ZONE_WIDTH = 26`px (full row height). Because the row box is full-bleed (§ Row Anatomy), `left-0` IS the physical sidebar edge — the zone needs no negative offset, so the coordinate expression is a plain `left-0` overlay. The zone's absolute span (sidebar x = 0…26) is 26px of the true sidebar edge. The palette-icon home is a 12px band (`ICON_ZONE_WIDTH = 12`) inset `ICON_EDGE_INSET = 10`px off the physical edge (sidebar x = 10…22) — past the widest (double, 2+6=8px) marker stripe, so the hover icon sits beside the stripe rather than over it. The button content is padded clear with `pl-[30px]` (12px hierarchy indent + 18px content padding) so the leading StatusDot + name start 4px past the zone's inner edge — the dot keeps its own hover-card and click-to-select, and the dot + name keep their exact x-positions (no content shift). Active on coarse pointers — touch gets direct label access (no `coarse:pointer-events-none`).

-**Hover affordance — palette icon + two-stage zone glow**: at rest the zone is transparent with no icon. On ROW hover (`group-hover`) the shipped `PaletteIcon` (~11px, in the 12px icon zone at `left: ICON_EDGE_INSET = 10`px, beside the edge-anchored stripe rather than over it) fades to ~65% and the whole zone glows ~12% family color; when the ZONE ITSELF is hovered the icon reaches full opacity and the glow deepens to ~24% (`color-mix`). The icon is drawn in the row's guarded family color (`markerColor`) on colored rows and inherited monochrome on uncolored rows. The icon container keeps an explicit `z-10` (the stripe is a DOM sibling rendered before it) as a guard so any residual overlap layers icon-over-stripe deterministically inside the zone's own `z-20` stacking context, not by incidental sibling order. `aria-label="Set window label"` names the zone for pointer AT users and test selection.

-**Marker stripe is display-only**: the marker renders as a left-edge stripe (3px dotted / 3px solid / 6px double in the guarded family color, gray uncolored) via the shared `markerStripeStyle` helper, anchored near-flush at the sidebar's physical left edge — `left: STRIPE_EDGE_INSET = 2`px (`window-row.tsx:474`, `:530`), `right: 0`. `dotted` is a fixed-rhythm `repeating-linear-gradient` (3px dash / 3px gap, `background-size: 3px 100%`), NOT `border-left: dotted` — a dotted border distributes dots per-element and restarts at every row, so stacked dotted rows showed seams while solid/double merged; the gradient's 6px period divides the 24px (36px coarse) row height exactly, so the rhythm carries across adjacent rows. It is purely a display of current state — clicking it opens the picker; it does not cycle. `themes.ts` owns `MARKER_STATES = ["", "dotted", "solid", "double"]` and the `markerStripeStyle(state, color)` helper, shared by this stripe and the Label picker's marker cells so the stripe vocabulary lives in exactly one place. Markers are available on all rows including uncolored ones.

 **Marker/color plumbing**: `WindowInfo.marker?: string` (`src/types.ts`) carries the state from the `@rk_marker` window option (architecture.md § `@rk_marker`). `setWindowMarker(server, windowId, marker | null)` in `client.ts` delegates to `setWindowOptions({"@rk_marker": ...})` (empty/`null` clears). `sidebar/index.tsx` owns `onColorChange` + `onMarkerChange` handlers, prop-drilled through `ServerGroup` to `WindowRow`; the Label picker passes the **exact** picked color and marker state straight to these (no cycling — any state is one click). The `Window: Label` palette action opens this same picker via an imperative `label-popover:open` CustomEvent that the matching `WindowRow` listens for (`{ detail: { server, windowId } }`, mirroring the `pin-popover:open` pattern); the row registers both listeners in one `useEffect`. **Scope: window rows only** — session rows and server tiles get the owned-palette color affordance but no marker and no left-edge label zone.
