Port the applicable @cloudflare/kumo@2.9.1 fixes: dark-mode favicon support, the updated collapsible default panel structure and styling, and transparent Tabs overflow scrims.

Port the @cloudflare/kumo@2.8.0 → @cloudflare/kumo@2.9.0 release delta into Svelte. The entries below intentionally follow Kumo's 2.9 changelog structure; React-only and build-system-only changes are called out where Svelte has a different equivalent.

## Minor Changes

• ff8ad54 — Banner contrast, status tokens, compact sizing, and actions: port the updated semantic status tokens and apply them across Banner, Badge, Toasty, and Command Palette highlighting. Add Banner.Action with primary, secondary, and ghost accent variants, Banner's size="base" | "sm" API, compact layout behavior, and inherited CTA sizing.
• f919182 — Chart loading states: replace the animated wave loader with a static reduced-motion-aware TimeseriesChart skeleton that matches line and bar chart types. Add loading placeholders to the Svelte ChartLegend API for both its compact and large variants.
• 535d579 — Disabled LinkButton: add disabled support that renders a real disabled button, removes anchor-only behavior, suppresses activation handlers, and supports explanatory title tooltips.
• aae94f1 — LinkButton title tooltip: wrap titled enabled LinkButtons in the same styled Tooltip behavior used by Button instead of relying only on the native title attribute.
• 9e083d2 — Full-screen mobile Sidebar: add fullScreenOnMobile, suppress the backdrop and divider when enabled, add Sidebar.Close, and fix Breadcrumbs.Link so ancestor crumbs keep their width while only the current crumb truncates.
• 51aa44c — Sidebar.Loading: add grouped, collapse-aware navigation skeleton rows built from SkeletonLine, with role="status" and a configurable accessible label.
• 86ee08c — Table-of-contents scroll tracking: add the SSR-safe useTableOfContentsActiveId hook with IntersectionObserver tracking, fixed-header offsets, custom roots, hash deep links, click pinning, scroll settling, and reactive section-id updates.
• 87d1ebc — Published output: the Svelte package already uses svelte-package and ships readable generated output without the React/Vite dist layout, so no React-specific dist or declaration-map change was copied.

## Patch Changes

• fc5e222 — Button accessible-name fallback: use a string or numeric Button title as the accessible label when the button has no text children.
• 8e71b38 — Prettier update: no runtime port was required; the Svelte workspace retains its existing formatting toolchain.
• 2a463f7 — Timeseries tooltip boundary: prevent tooltips from remaining visible outside the chart after browser context-menu interactions, with the Svelte fallback closing on outside pointer movement.
• 0f0c44d — ClipboardText feedback: keep the check icon until the final copy settles, reuse the anchored copied feedback instead of stacking it, and bump the open feedback on repeated clicks with reduced-motion support.
• b171c71 — Compact Banner Link actions: render Kumo Link actions inline with compact Banner text while keeping CTA button actions trailing; the Svelte implementation detects the rendered Kumo Link and preserves the action snippet API.
• 4f0ed75 — Purple Badge fallbacks: use the corrected purple OKLCH fallback colors in the Svelte theme.
• 5efe6dd — Flow.Node render lint rule: Svelte Flow.Node uses snippet children rather than React's render prop; its existing rest-prop forwarding is the Svelte equivalent, so no JSX-specific lint rule is added.
• 32b2168 — Timeseries brush persistence: restore the brush-to-zoom cursor after ECharts options are replaced.
• b0870e1 — Flat InputGroup controls: remove shadow-xs from both InputGroup and nested InputGroup.Button so grouped controls match standalone inputs.
• 34e1672 — Library bundling: the Svelte package's svelte-package build already owns entry generation and declaration output; no Vite/tsdown-specific React bundler change applies.
• 2575f9c — Muted Timeseries chrome: apply Kumo-muted colors to Timeseries axes, labels, names, and horizontal gridlines.
• 7c33107 — Repository formatting: no functional Svelte change; formatting remains governed by the existing Svelte workspace pipeline.
• ee6e569 — Typography line heights: set default text-base and text-lg line heights to 1.5.
• 927d19f — Inert utility classes: remove redundant bare ring/outline utilities from the Svelte equivalents while retaining their explicit width and color utilities.
• 924f07a — Base UI chunking: no direct Svelte equivalent; Svelte consumers use the package's existing bits-ui dependency graph rather than Kumo's React vendor chunk.
• 7ef8c46 — Tabs overflow rails: add accessible start/end scroll buttons with customizable labels, scroll-bound visibility, gradient edge affordances, and smooth scrolling for both tab variants.
• 86afc2b — Disabled/loading Button tooltips: show title tooltips through an enabled wrapper when the actual Button cannot receive pointer events.
• 5516c22 — Command Palette highlight contrast: use the stronger warning highlight background and default text contrast for matched ranges.
• 24149b9 — Tailwind class sorting: no runtime Svelte behavior changes; the workspace's existing formatter/linter remains the source of truth.
• 8de0551 — Vite+ toolchain migration: not copied because the Svelte port has its own Vite/SvelteKit build and test pipeline.
• 60f5bfa — Full type checking: the Svelte package already runs full svelte-check-native validation in its package build; no React CLI entrypoint change applies.

Restore the upstream Flow layout rewrite with dedicated layout utilities and regression coverage.

Add auto-resizing support to InputArea.

Add reference markers to TimeseriesChart.

Add horizontal threshold lines to TimeseriesChart.

Include chart components exported from the shared chart barrel in the generated component registry.

Split the docs deployment build from the npm package build to reduce Cloudflare build time.

Add target support to Sidebar.MenuSubButton links.

Keep the mobile Sidebar open when focus moves to portaled interactive content.

Disable sidebar menu button tooltips while the sidebar is expanded.

Port upstream Kumo map, vertical Flow, Dropdown, Button, and class-merging updates after June 25, 2026.

feat(chart): add BubbleMap chart component

New BubbleMap component renders proportional bubbles over a registered geographic map using ECharts' scatter series. Includes value-based radius scaling, a mapColors palette addition to ChartPalette, and supporting types. Also extracts escapeHtml / defaultValueFormat tooltip helpers into a shared tooltip-utils module reused by SankeyChart.

Keep primary and destructive button active/focus rings matched to their variant color.

Fix toolbar input-group active highlights and align the homepage toolbar demo actions.

Use the Button component for Toast close controls and match the hover tint to the toast variant.

Fix Dialog size prop to set a fixed width instead of only a minimum width. Previously, dialog content could stretch the dialog beyond its intended size.

Align Kumo 2.6 prop documentation metadata for chart, radio, and toolbar APIs.

Remove the duplicate InputGroup outline from toolbar input group focus states.

Stabilize dialog variant exports so fixed-width dialog sizing can be tested without mounting dialog overlays.

Port Kumo 2.6 updates, including Toolbar, chart legend interactions, button token styling, sidebar overflow fixes, and typed radio values.

Fix documentation GitHub source links so they point to files under the package directory.

Update dependencies under the three-day minimum release age policy and refresh security overrides for transitive advisories.

Port May 15+ upstream Kumo updates including Badge dot appearance, broader code language aliases, tooltip viewport width constraints, and form error ring parity.

Expand generated component registry coverage, changelog pagination, and Svelte docs demos for command palette, popover, sidebar, and table surfaces.

Align component API reference props and missing Svelte component prop support with upstream Kumo.
