💡 What is the current behavior?

ix-application component doesn't provide default skip-link or api for bypass mechanism for skipping repeated content.

🆕 What is the new behavior?

Add default-on skip links to ix-application for bypassing repeated application-shell content. The list includes Main and, when footer content is present, Footer destinations, with configurable Main targeting, accessible focus and scroll management, localized labels, and an explicit opt-out for applications providing their own bypass mechanism.

📝 Walkthrough

Walkthrough

ix-application now provides a default-on, configurable skip link with localization, target validation, focus and scroll handling, opt-out support, styling, framework bindings, preview wiring, and regression coverage.

Changes

Application skip-link support

Layer / File(s) Summary
Skip-link contract and implementation
packages/core/src/components/application/*, packages/core/src/components.d.ts, packages/angular/src/components.ts, packages/core/component-api.json
ix-application exposes skip-link properties, resolves and validates targets, manages focus and scrolling, renders the link, and preserves existing menu behavior.
Skip-link presentation and target wiring
packages/core/src/components/application/application.scss, packages/*-test-app/src/preview-examples/*, .changeset/*
The skip link uses themed LTR and RTL focus styles. Framework previews configure main-content as the target. The changeset documents the minor release.
Component regression coverage
packages/core/src/components/application/test/*, packages/core/src/components/menu*/test/*
Tests cover rendering, keyboard order, visibility, focus and scroll behavior, invalid targets, localization, disabling, teardown, and menu navigation.
Framework and visual validation
testing/framework-tests/*, testing/visual-testing/*, packages/storybook-docs/src/stories/application/accessibility/*
ARIA snapshots, Playwright tests, and Storybook stories cover rendering, axe checks, activation, target focus, configuration variants, and focused visual presentation.

Estimated code review effort: 4 (Complex) | ~45 minutes

Mergeability Score: 🟡 Moderate · up to 825b5

The external bypass-link example can scroll to the target without moving keyboard focus into the application content, which can leave keyboard users before the repeated shell content. Make the destination focusable before merging.

In `@packages/core/src/components/application/application.scss`:
- Around line 33-36: Remove the empty line between the z-index and padding
declarations in the application styles so padding immediately follows z-index
and satisfies the declaration-empty-line-before lint rule.
- Around line 28-32: Update the multiline calc() expressions in the application
styles, including the inset-inline-start declarations near the referenced
sections, to place each + operator at the beginning of the following line rather
than leaving it at the end of the preceding line. Preserve the existing values
and formatting otherwise so stylelint no longer reports
scss/operator-no-newline-after violations.

In `@packages/core/src/components/application/application.tsx`:
- Around line 213-251: Update focusCustomSkipLinkTarget and
restoreTemporaryTargetFocusability so each temporary target’s blur listener
captures and restores that specific target rather than reading the shared
temporaryFocusTarget at event time. Ensure switching focus from one custom
target to another cleans up the previous target independently, removes only its
own listener and temporary tabindex, and preserves the current target’s cleanup
state.
- Around line 193-211: Update findCustomSkipLinkTarget to query only elements
matching the requested targetId using a properly escaped attribute selector,
while preserving the existing isOwnedLightDomDescendant check, uniqueness
validation, usability validation, warning, and fallback behavior.

In `@packages/core/src/components/application/test/application.ct.ts`:
- Around line 86-89: Update the outlineInset calculation in the link.evaluate
callback to use Number.parseFloat for both style.outlineWidth and
style.outlineOffset, replacing the global parseFloat calls without changing the
calculation.

In `@testing/visual-testing/tests/application/application.e2e.ts`:
- Around line 13-26: Update the focused skip-link regression test to execute for
theme-classic-light, theme-classic-dark, and the brand theme, reusing the
existing navigation, viewport, focus assertions, and screenshot configuration
for each variant.

Use the correct @since version for these new ix-application props.

@siemens/ix is currently 5.1.1, and the changeset for this skip-link API is a minor change, so the new disableSkipLink, i18nSkipToContent, and skipLinkTargetId props should use the next released minor version, not 5.2.0.

Please add packages/storybook-docs/src/stories/application/accessibility/a11y-application.stories.ts (i.e. same pattern as a11y-menu.stories.ts) with a11y: { test: 'error' }.
Cover default skip link, skipLinkTargetId, disableSkipLink, and i18nSkipToContent, etc.
This is a user-visible keyboard interaction, not an internal refactor. See .github/instructions/code-review.instructions.md (Storybook)

Can we run axe while the skip link is focused? Off-screen, contrast/name of the visible state are not checked. Same for application-skip-link-axe.spec.ts. See .github/instructions/code-review.instructions.md (Accessibility)
