 Dormouse is a tenant in someone else's house. The house is VSCode. The user picked the furniture (their theme), the lighting (their mode), the typography (their editor font). Dormouse moves in, multiplies what the user can do with their terminals, and leaves the decor alone. The interface should be indistinguishable from a built-in panel: not because it imitates VSCode, but because it inherits from VSCode. Every color, every font, every surface is a passthrough of the host's tokens.

 - **Surface:** `bg-door-bg` + `text-door-fg`. These resolve at runtime via `computeDynamicPalette()` and may match either the inactive-header palette or the terminal palette, whichever has stronger separation from `app-bg`.
 - **Dimensions:** `h-6` (24px), `min-w-[68px]`, `max-w-[220px]`; the title button pads `pl-2.5` (10px), `gap-2` between its glyph, title, and badges, ending `pr-2.5` alone or `pr-1` when the notepad button follows it. The notepad button carries the trailing inset itself (`pl-0.5 pr-2`).
 - **Type:** `text-sm font-medium font-mono`.
-- **Content:** leading browser-display icon cluster on a browser Surface (`size={12}` each, `gap-0.5` — a wide robot plus the presentation glyph, or the presentation glyph alone for `iframe`; named in the Door's accessible name, `docs/specs/dor-browser.md` → Browser Chrome); truncated title; optional TODO pill (`text-xs font-semibold tracking-[0.08em]`, success-tinted when flourishing); optional bell icon (`size={11}`, `weight="fill"`), `text-alarm-vs-door` when ringing; trailing notepad button (`size={12}`, `weight="fill"`) when the minimized Surface holds notes.
-- **Alarm:** one 2px inset overlay (`--color-alarm-vs-door`) draws the edge for both the unlabelled ring, where it flashes once on arrival, and `SPOKEN`, which persists until the ring is attended and adds a speaker icon *beside* the TODO pill and bell instead of evicting them. `SPEAKING` instead inverts and pulses the whole Door and takes the badge slot for its speaker-plus-label, for one utterance. Both speech states carry a speaker icon (shape, not color); all three name the state in the accessible name. The row inventory is `docs/specs/layout.md` → Alarm overlay.

The door is a labelled `role="group"` wrapper holding one or two buttons rather than one button — the title button reattaches, the notepad button opens the popover and does not (`docs/specs/notepad.md` → Notepad UI) — and only the notepad button takes the standard `hover:bg-current/10` wash.

 - **Color:** `text-inherit` — inherits the header's foreground, so it tints with the active/inactive header palette.
 - **Hover:** `hover:bg-current/10` — a 10%-opacity wash of the current text color. Theme-agnostic, works light or dark.

 The flat segments inside a `PopupButtonRow` — the row owns the border, background, shadow, and `text-sm`, so a segment contributes only padding and state. Every segment currently inherits the row's foreground; these rows offer rather than ask, so none of them carries an emphasized action.
