feat(ui): build LayoutSplitter and CustomScrollbar for real

Both advertised behaviour they did not have. LayoutSplitter declared
resizeStart, resize and resizeEnd with no pointer handling whatsoever, so a
caller wired up @resize and received nothing, for ever, with no error, and its
props were columns, gap and maxWidth copied from a grid scaffold.
CustomScrollbar was the same shape with a scroll output.

The splitter now resizes. Dragging lives in the reactive runtime behind
data-wrn-splitter, because a pointermove fires far too often to route through
a client function and a state write made in that callback is dropped; the
resolved size is held on the container as a --wrn-split custom property and
the component grids from it. The handle is a real separator: arrow keys step
it, Home and End go to the bounds rather than to nothing, and it carries
aria-valuenow, aria-valuemin and aria-valuemax. minSize fixes both bounds so
neither pane can be dragged away and left unrecoverable.

CustomScrollbar is CSS rather than script -- scrollbar-width and
scrollbar-color with webkit rules for the engines that still need them -- and
its fake scroll output is removed rather than left unimplemented, since a
caller can listen for a plain scroll event.

The test harness needed a fix too: mount did not bind the window CustomEvent,
so the runtime built events from the host global and happy-dom listeners never
matched them, which made anything dispatched look silently lost.

+# Layout and page-structure components — design
+
+Date: 2026-08-08
+Status: approved, not yet implemented
+
+## Problem
+
+Two problems, in different proportions to the navigation group.
+
+**Three components advertise behaviour they do not have.**
+
+`LayoutSplitter` is the worst component in the library. It declares
+`resizeStart`, `resize` and `resizeEnd`, so a caller reasonably wires up
+`@resize` and receives nothing, forever, with no error. It has no pointer
+handling at all, and its props are `columns`, `gap` and `maxWidth`, copied
+wholesale from a grid scaffold. `CustomScrollbar` is the same shape: a
+`scroll` output, no behaviour, and the same wrong grid props.
+
+`Kbd` is nine lines, but that is not the same failure — a `<kbd>` element
+genuinely does not need more. It is thin, not dishonest.
+
+**Most of the group is built on Tailwind utilities.**
+
+Seven of the ten use utility classes and `class:` conditionals rather than
+`wire-*` classes and a local style block. They are theme-aware, because the
+utilities carry arbitrary values bound to tokens
+(`bg-[var(--wire-color-surface-soft)]`), but they depend on Tailwind being
+present and produce a class explosion. `SectionHeader` has 38 such lines.
+
+A correction that shaped this survey: when Tabs was rewritten it was described
+as "the only component in the library using Tailwind utility classes". That
+was wrong. **20 of 108 do**, and seven of those are in this group.
+
+## Scope
+
+The ten layout components plus the four page and section primitives, because
+the goal is composing whole pages and the section-level pieces live in other
+categories:
+
+|                  |                                                                                                  |
+| ---------------- | ------------------------------------------------------------------------------------------------ |
+| Layout           | Container, Columns, Grid, LayoutSplitter, Typography, Image, Link, Divider, Kbd, CustomScrollbar |
+| Page and section | Section, SectionHeader, PageHeader, PublicPageShell                                              |
+
+`PageHeader` is already on the target convention — 696 lines, its own style
+block, zero Tailwind. It is the model the rest migrate toward, and it needs an
+audit rather than a rewrite.
+
+## Decisions
+
+### Styling
+
+Every component in scope moves to `wire-*` classes with a local `style {}`
+block and `data-*` attributes for variants, matching PageHeader, DataTable,
+Toaster and the navigation group.
+
+Variants become data attributes rather than `class:` conditionals, so
+`variant="soft"` renders `data-variant="soft"` and the style block selects on
+it. That replaces roughly a dozen `class:` lines per component with one
+attribute and a handful of rules.
+
+Tailwind stays available to applications. This is about the shipped library
+not requiring it.
+
+### LayoutSplitter
+
+Real resizing, driven from the reactive runtime by a declarative attribute:
+
+- `data-wrn-splitter="horizontal|vertical"` on the container
+- `data-wrn-splitter-handle` on the divider
+- the runtime writes the resolved size onto the container as a CSS custom
+  property, so the component styles from it
+
+Pointer events fire far too often to route through client functions, and drag
+state written inside a `pointermove` callback is dropped — the same constraint
+that put roving focus and scrollspy in the runtime.
+
+Keyboard support is part of the contract, not an extra: arrow keys move the
+divider by a step, Home and End jump to the bounds, and the handle carries
+`role="separator"` with `aria-valuenow`, `aria-valuemin` and `aria-valuemax`.
+
+Sizes are clamped to a `minSize` per pane so a pane cannot be dragged to
+nothing and become unrecoverable.
+
+### CustomScrollbar
+
+Scrollbar styling is CSS: `scrollbar-width` and `scrollbar-color` for the
+standard property, with `::-webkit-scrollbar` rules for browsers that still
+need them. No runtime, no scroll output — the existing `scroll` output is
+removed rather than left unimplemented, since a caller can listen for a plain
+`scroll` event on the element.
+
+Its grid props (`columns`, `gap`, `maxWidth`) are replaced with ones that mean
+something: `axis`, `thickness`, `thumb`, `track`, `maxHeight`.
+
+### Kbd
+
+Left as it is, beyond the `wire-*` migration. It is thin because a `<kbd>`
+is thin.
+
+### Runtime budget
+
+The splitter is roughly 2k minified against 67.7k of an 80k budget. It fits.
+The budget now measures minified output, so comments cost nothing.
+
+## Components
+
+| Component       | Work                                                                                                                             |
+| --------------- | -------------------------------------------------------------------------------------------------------------------------------- |
+| LayoutSplitter  | Build. Runtime-driven pointer resize, keyboard steps, `role="separator"` with value attributes, per-pane `minSize`, real outputs |
+| CustomScrollbar | Build. Themed scrollbar styling, meaningful props, the fake `scroll` output removed                                              |
+| Container       | Migrate. `maxWidth`, `padding`, `centered` as data attributes                                                                    |
+| Columns         | Migrate. `columns`, `gap`, responsive collapse in a media query rather than `md:` prefixes                                       |
+| Grid            | Migrate. `columns`, `gap`, `minItemWidth` for an auto-fit track                                                                  |
+| Typography      | Migrate the remaining Tailwind lines into its existing style block                                                               |
+| Image           | Migrate. `ratio`, `fit`, `rounded`, `loading`                                                                                    |
+| Link            | Migrate. `variant`, `underline`, external-link affordance                                                                        |
+| Divider         | Migrate. `orientation`, `variant`, optional label                                                                                |
+| Kbd             | Migrate only                                                                                                                     |
+| Section         | Migrate. `spacing`, `variant`, `color` as data attributes                                                                        |
+| SectionHeader   | Migrate. Its 38 Tailwind lines collapse into a style block                                                                       |
+| PublicPageShell | Migrate. `minHeight`, `overflow`, `background`, `headerOffset`                                                                   |
+| PageHeader      | Audit only — already on the convention                                                                                           |
+
+Component count stays at 108; every file already exists.
+
+## Data flow
+
+Props in, outputs out, no global state. The splitter is the only component
+with runtime state, and that state lives in the DOM as a custom property
+rather than in component state.
+
+## Error handling
+
+Numeric props (`columns`, `minSize`, `thickness`) clamp rather than throw,
+because they arrive as HTML attributes. A splitter with one child renders that
+child full width instead of erroring.
+
+## Testing
+
+- Per-component entries in `packages/ui/test/ui.test.ts`
+- Splitter drag and keyboard covered in `packages/csr/test/reactive.test.ts`,
+  using markers rather than measured size: the test DOM reports every element
+  as zero-sized
+- Showcase profiles for each, so every component gets live demos
+- Regenerate the component reference **before** the showcase — the generator
+  cannot see new props otherwise
+- Each phase ends with `bun run check:production` green
+
+## Phases
+
+1. **Scaffolds** — splitter runtime and component, CustomScrollbar
+2. **Layout migration** — Container, Columns, Grid, Divider, Image, Link,
+   Typography, Kbd
+3. **Page and section** — Section, SectionHeader, PublicPageShell, PageHeader
+   audit, plus a page in `examples/basic-app` composing the whole set
+
+## Risks
+
+- The migration rewrites working markup. Visual regressions are the main
+  danger, and the browser pane cannot take screenshots, so verification is
+  computed styles and the UI visual contract rather than eyes on pixels.
+- Removing `class:` conditionals changes the rendered class list, so any
+  application selecting on those utility classes breaks. This needs a
+  migration entry alongside the Tabs and Sidebar changes already outstanding.
+
+## Codebase constraints to respect
+
+- No apostrophes in `.wrn` comments
+- `/* */` only inside style blocks; `//` silently eats the next CSS rule
+- Block comments are not allowed inside `props {}` — line comments only
+- `data-show` takes a bare expression, not `{...}`
+- One root element per component
+- No deferred state writes in client functions
+- Object props are passed through state, never inline braces in an attribute
+- Package components need explicit imports
+- Stop the dev server before running tests; it wipes `.wrnexus`
+- Restart the dev server after changing a package component
