feat(android): the tap highlight goes, a press state replaces it

The phone drew a grey box over the bounding rect of whatever was
tapped, which is the web view saying what it is. It is gone in one
declaration: `-webkit-tap-highlight-color` is inherited and an
inherited property crosses a shadow boundary, so `html` in index.css
reaches every shadow root in the app. Measured three roots deep,
rgba(0, 0, 0, 0.18) before and rgba(0, 0, 0, 0) after.

Removing it removes the only touch feedback several surfaces had, so
the press state is part of the same change rather than a later polish
item — with the highlight gone a held row measured the *hover* tint,
which on a phone is synthesised by the hold itself and outlives it.
The four lists' rows, the tab bar, the sidebar's destinations and the
shared context-menu item take --yj-press-overlay on :active; the cards
already had scale(0.97). The press selector carries a state class
because a row is .track-row.selected.active, so a bare :active shows
nothing on the row a phone is most likely to press. And those
surfaces' hover tints move behind (hover: hover) and (pointer: fine),
which is #68's gate applied to a tint rather than a revealed control.

user-select, the other half of the Findings, was already done: the
first rule in index.css covers the shadow roots for the same reason.
touch-action: manipulation is declined — the 300ms delay it is offered
for is already absent on a width=device-width viewport, and what it
would really change is the gesture stack tuned by measurement on a
device this session cannot measure.

Closes #54

+## The visual tier does not gate, and that is measured (#196)
+
+`make ui-visual` is the same suite with nine `toMatchScreenshot`
+baselines switched on. **Nothing runs it but a person**, deliberately,
+and the reason is a number rather than a preference: the committed
+baselines were recorded on Arch, and replayed in a bare `ubuntu:24.04`
+container — CI's `check` image — three of them fail for reasons that
+have nothing to do with any component.
+
+| baseline | Arch | ubuntu:24.04 |
+|---|---|---|
+| `page-header` filtered-by-search | passes | ratio 0.03 differ, against a 0.02 allowance |
+| `track-info` | passes | ratio 0.03 differ |
+| `seek-bar` | 1152×18 | 1152×17 |
+
+The two references that were genuinely stale did not even agree about
+their *new* size — `now-playing` renders 1152×65 on Arch and 1152×64 in
+the container. So moving CI's `check` job from `make ui-test` to
+`make ui-visual` is not a one-line change: it needs a second,
+container-recorded baseline set, which every local run would then fail
+against. That is the same trap the other way round, and a pre-push hook
+is the same fault again — one machine's baselines against everybody
+else's renderer.
+
+So the tier stays local and opt-in, and the rule that replaces the gate
+is:
+
+- **A change that moves a component's geometry refreshes that
+  component's reference in the same commit, having read the image.**
+  Look at the PNG; the dimensions in the failure message are the cheap
+  half of the answer.
+- **Never refresh a reference you did not cause.** #196 exists because
+  four of them drifted across three unrelated merges, and every red run
+  made the next person likelier to stop running the tier than to read
+  it.
+- **State the world the shot is taken in.** The stores are singletons,
+  so a visual case that sets nothing photographs whatever the previous
+  case left behind — which is how the sidebar's baseline came to have
+  Tracks lit and `now-playing`'s to be playing from a dynamic mix.
+- **Record one file with `make ui-visual-update UI_ARGS=<path>`**, and
+  check `git status` before committing either way. That filter is only
+  honoured since #204: the recipe was a bare `--update`, and vitest
+  takes the following positional as the flag's value, so the path was
+  swallowed and *every* baseline was re-recorded — blessing any stale
+  one in silence.
+
+What the tier is worth, for the record: it is a *layout* check, blind to
+colour (the component tier has no `:root`, so it renders the fallbacks —
+`make ui-visual` passed unchanged through a whole palette rewrite,
+twice), and it has caught one thing nothing else could — swapping
+`library-status-indicator`'s `<button>` for a `<span>` lost the UA
+stylesheet's `box-sizing` and grew the badge 36→38px.

+
+| menu | items | first item top | last item bottom |
+|---|---|---|---|
+| queue panel | 7 | 95 | 431 |
+| track list | 8 | 86 | **470** |
+
+The viewport is 439. So the track list's last item — "Remove from
+Library" — is below the fold. It is **not unreachable**: the sheet is a
+`wa-dialog` whose body is `overflow-y: auto`, measured `scrollHeight`
+412 against `clientHeight` 373, and scrolling it 39px brings that item
+fully into view (383–431). What it has is no *affordance*: nothing on
+screen says the list continues.
+
+Two things worth knowing before adding a ninth item anywhere.
+
+**The limit was already reached, and this is what crossed it.** Seven
+48px rows in a 373px body is 364px — the queue's menu fits with 8px to
+spare and the track list's fitted exactly. Any item added to any of the
+fourteen menus after #60 was going to be the one that overflowed; the
+first one simply happened to be this.
+
+**The measurement has to be taken with a row selected**, since the
+`Go to` items are drawn for a single selection only, and on the *first*
+track of the fixture library — which has no album (`01 Tone A`,
+`02 Tone B`) — only "Go to Artist" appears. That is the 8 above; an
+ordinary track makes it 9.
+
+Filed as its own issue rather than fixed in #67's diff: it is a
+property of the shared sheet (`components/menu-surface/`), not of the
+items.
+
+## The tap highlight is one inherited declaration (measured 2026-08-24)
+
+`-webkit-tap-highlight-color` is an **inherited** property, and an
+inherited property crosses a shadow boundary — so `html { … :
+transparent }` in `index.css` reaches every shadow root in the app and
+no component needs a rule of its own. Measured in the running app
+(Chromium, `app-sidebar`'s `li button`, which is three shadow roots
+from the document): `rgba(0, 0, 0, 0)` with the rule, and
+`rgba(0, 0, 0, 0.18)` with it removed. That 0.18 grey over the bounding
+rect of whatever was tapped is what #54 reported.
+
+The same argument was already spent once and is worth not
+re-deriving: `index.css`'s first rule is `*, *::before, *::after {
+user-select: none }`, which for the same reason already covers the
+shadow roots — #54's Findings ask for `user-select` on interactive
+surfaces and it has been done since before the issue was filed.
+
+**What the highlight was, on the surfaces that had nothing else, is the
+press feedback.** Measured on a track row with the press rule removed
+and the button held down: `rgba(255, 255, 255, 0.05)` — the *hover*
+tint, arriving because the pointer is over the row, which is a
+synthesised hover on a phone and outlives the press. With the rule:
+0.12 while held, and the neighbouring row unchanged. So the press state
+is part of removing the highlight rather than a separate polish item,
+and the hover tints on those same surfaces moved behind
+`(hover: hover) and (pointer: fine)`, which is #68's gate applied to a
+tint rather than to a revealed control.
+
+**`touch-action: manipulation` was considered and not taken.** The
+Findings offer it for the 300ms tap delay; this app's viewport is
+`width=device-width`, which is what removes that delay in Chrome, so
+the stated benefit is not there to win. What it would change is the

+ * What a tap looks like now that the web view's own highlight is gone
+ * (#54).
+ *
+ * `index.css` sets `-webkit-tap-highlight-color: transparent` on
+ * `html`, which — the property being inherited — reaches every shadow
+ * root in the app. That takes away the grey box a phone drew over the
+ * bounding rect of whatever was tapped, and with it the only touch
+ * feedback the rows, the tab bar, the sidebar's destinations and the
+ * shared menu items had. So the press states below are not decoration:
+ * without them this change trades wrong feedback for none.
+ *
+ * **Asserted against the parsed stylesheet**, on `hover-affordance`'s
+ * precedent and with the same limitation stated out loud: CDP's
+ * `Emulation.setEmulatedMedia` does not reach this tier's iframe, so
+ * there is no way here to render a component as a phone would, and
+ * `:active` cannot be forced from a test either. What the browser will
+ * answer is the shape it built from the `css` literal — which rule sits
+ * inside which media query, and what the press selector actually is.
+ *
+ * Two regressions are worth catching that way, and both are silent on a
+ * desktop:
+ *
+ * - someone hoisting a hover tint back out of its query as a tidy-up,
+ *   which on a phone is a highlight that arrives because a finger
+ *   touched the row and stays after it has gone;
+ * - someone simplifying the press selector to a bare `:active`, which
+ *   is one class short of `.selected` / `.active` and so does nothing
+ *   on the row a phone is most likely to press — the one it has just
+ *   selected.
+ *
+ * The pixels are the Android tier's, and the tap highlight itself is
+ * `e2e/specs/native-touch-feel.spec.ts`, since only the real app loads
+ * `index.css` at all.
