The phone's top bar is about to go, and the search box is the one thing
in it that is an action rather than chrome. It becomes a button in the
row that already says which page you are on, opening a wa-dialog with
the real search box in it.
Three decisions worth the words.
**A wa-dialog, and that is a mechanism rather than a taste.** wa-popup
renders `<div popover="manual">` and feature-detects the Popover API,
falling back to `strategy: "fixed"` where there is none -- which is
Chrome 113, the reference device, since `popover` is Chrome 114. And
`position: fixed` escapes ancestor overflow but not `contain: paint`,
which `.main-panel` carries, so a popup-shaped search panel opened from
a view's header is structurally clipped on that device. `<dialog>` /
`showModal()` is Chrome 37 and uses the real top layer. No tier here can
see the difference -- CI's Chromium and WebKit both have the Popover
API -- so the component test asserts the *mechanism*, a native
`<dialog>` in the tree, rather than the symptom.
**An element, not a PageAction.** Two of the seven searchable views are
detail views with no page-header; they filter on the term and say so in
their own headers. Declaring search as an action would mean seven hosts
each writing it out, which is a second list of searchable views, and it
would put a phone mode for actions inside page-header, which that
component documents its refusal to grow. search-store's own map is the
condition, asked by one component placed three times.
**The modal carries the real search-bar**, so there is still one
debounce, one clear button and one view-scoped placeholder. Escape
closes it and *keeps* the term -- the input treats Escape as "clear the
search", which is right in a header where the box stays on screen and
wrong in a surface whose dismissal would then discard the search.
Plan 016 B2, phase 1. Below 600px the grid drops its sidebar column,
`bottom-nav` becomes the primary navigation, and the shell fits the
viewport instead of scrolling sideways out of it.
600 rather than the sidebar's own 900, because 900 is a laptop and the
answer there is a narrower sidebar, which is still a sidebar. Under 600
there is no room for one at all: 360px of viewport over a 200px nav is
not a layout.
**The tab bar is four destinations and a way to everything else.**
Three to five is where touch targets stop being thumb-sized -- eleven
over 360px is 32px each -- so the four are the ones plan 016's subset
says a phone is for, and "More" opens the *existing* `app-sidebar` in a
drawer rather than listing the destinations a second time. Two lists is
two places to add the next view to.
That reuse has a cost this found the hard way: a shared component
brings its `data-testid`s with it, so rendering the drawer's sidebar
unconditionally put a second `nav-home` (and ten siblings) in the DOM
and **failed 30 existing specs** with "resolved to 2 elements" -- on a
desktop viewport, where this element is `display: none` and the drawer
can never open. It renders only while the drawer is open, and the
component test asserts the absence, because the failure is invisible
from inside the component and lands in files nobody touched.
**What made the shell overflow was minimums, not padding.** Measured at
360px: the body was 652px wide, because a `min-width` in a flex row is
a hard floor and a grid item's implicit minimum is its content. So
`min-width: 0` on the boxes between the viewport and the content, and
each component stands its own non-essential parts down in its *own*
stylesheet -- search-bar's 200px floor, job-indicator's label (the
visible one; the live region that announces it is untouched),
audio-player's seek bar and volume. A media query inside a shadow root
is answered by the viewport, so this is the component saying what it
drops rather than the shell reaching in.
Volume goes because the hardware keys own it on a phone, which is the
same reason mediacontrols' Android handler implements no volume
callback. Seeking goes because 4px is not a thumb target; it belongs to
the full-screen now-playing view, which is the next phase.
An existing spec therefore asserts the opposite of what it did:
layout-overflow's 320px case used to require that the 464px behind
`overflow: hidden` could be *scrolled to*, which was the remedy
available while the shell had one layout. It reflows now -- 320px in a
320px viewport, exactly -- and reflow is what WCAG 1.4.10 asked for.
Four views had a heading and four did not, two had a sort control and
none showed a count, so the app changed shape as you moved through it
and "how many albums have I got" could only be answered by counting.
The reason they disagreed is that each had written its own arrangement:
the sort toolbar existed three times, in track-list, cover-grid and
playlist-view, as the same twenty lines with different bugs.
<page-header> is that arrangement once - title, count, sort, actions -
and nine views adopt it. Artists and Genres gain the sort control they
never had; Artists sorts by name only, because library.Artist carries
nothing countable, so the header renders a label and a direction button
rather than a select with one option in it. The header keeps its place
while a view loads: a heading that appears only once the data does is
the shifting layout this is meant to stop. The count is omitted, not
zero, until the view has an answer.
The header search box keeps its slot on every view instead of vanishing
on the ones it cannot serve - which is what moved the library filter
and the job indicator on every navigation. It is view-scoped by
decision and now says so: "Search albums" in the placeholder, the scope
named in the header ("Showing artists matching 'tide'"), and disabled
with a reason where there is nothing to search or the page has a search
of its own.
Also fixes an e2e trap this uncovered: the view-lifecycle spec toggled
shuffle and never toggled it back, so a second run against the same app
failed playback.spec's shuffle assertion - a failure that reads exactly
like a regression in whatever you are holding.
- Sidebar: convert all em-based padding/gap to px values, icon sizes to --yj-icon-md
- Now-playing: cover placeholder icon to --yj-icon-lg, text sizes to type tokens
- Search-bar: search icon to --yj-icon-sm, input font to --yj-text-md
- Audio-player: convert em-based gap/padding/margin to px values
- Seek-bar: tooltip font to --yj-text-lg, margin from em to px
- Volume-control: padding/margin from em to px, thumb sizes from em to px
- All components import designTokens and include in static styles
- Library store notify() coalesces multiple calls per microtask tick into one subscriber notification
- Search input debounces store propagation by 150ms while keeping instant visual feedback
- Empty search input clears immediately for responsive UX
