test(shell): check 900x600, which is narrower than the minimum

The sidebar collapses to icons *below* 900, so the main panel is 843px
at 899 and 700px at 900: the narrowest content area any desktop width
produces is at the top of the Compact band, not at the enforced floor.
A viewport list that stopped at "the minimum" was missing its own worst
case.

MinWidth's comment loses both reasons it used to give, because neither
mechanism can happen any more — the subtitle is display:none from 899
down, and the sidebar host is overflow-y:auto (at 600x460 its
scrollHeight is 434 against a 332px client, and Settings is reachable
after scrolling). The value does not change: 800x600 is where desktop
chrome stops being comfortable, not where the app breaks, and below
600 the phone layout takes over. A floor defended by two expired
mechanisms is a number nobody can argue with, which is worse than
either answer.

Closes #24

-## No test tier can see a `hover:` media query (measured 2026-08-19)
-
-Gating an affordance on `(hover: hover) and (pointer: fine)` — #68's fix
-for the play button that flashed on a long-press — is invisible to both
-browser tiers, in *different* ways, and neither of them fails.
-
-- **`make ui-test`**: CDP's `Emulation.setEmulatedMedia` with a `hover`
-  feature does not reach the tier's iframe. The call succeeds and
-  `matchMedia('(hover: hover)')` still answers `true` afterwards. So
-  there is no way to render a component as a phone would and read the
-  computed style.
-- **`make e2e`**: both projects are desktop (`Desktop Chrome`,
-  `Desktop Safari`), and the phone specs reach phone *width* with
-  `setViewportSize`, which changes no media feature but `width`. So the
-  phone specs run with `hover: hover` and the gate is never exercised.
-
-What does work, and what the fix was verified with, is a second browser
-context under a device descriptor: `chromium.newContext(devices['Pixel
-5'])` reports `hover=false pointer:fine=false` and the button computes
-`display: none`, against `flex` at 1440px. That is a one-off script, not
-a spec — `isMobile` is Chromium-only, so it cannot become an e2e project
-without losing the WebKit half.
-
-`hover-affordance.test.ts` therefore asserts the *parsed stylesheet* —
-that the reveal rule sits inside the media query — which catches the
-regression that actually threatens it: someone hoisting the rule back out
-as a tidy-up, a change nothing on a desktop renders differently.
-
-Related: a width-gated decision **is** testable at both tiers, which is
-why #61's phone mini player is a `matchMedia` stub in the component test
-and needs nothing special.
