HTML5 forbids interactive content (<button>, <a>, <input>...) as descendants
of <a>. The original <a href=…><button>✓</button></a> markup triggered two
concrete bugs flagged by Felix, Nora, and Leonie in PR #288 review:
- Browsers inconsistently route the nested click: on some engines the
stopPropagation() still bubbles, and the user navigates into the document
instead of dismissing.
- The senior audience (60+) tap-selects with a slight drag, and the OS
treats the interaction as anchor vs. button inconsistently — a
reproducible usability failure Leonie has seen in testing before.
Refactor to the Option-C layout from issue #285 comment #3573: outer <li>
flex container, <a> wrapping avatar + body + time, <button> as a sibling.
Independent focus stops, invalid-HTML gone, no behavioural regression.
A new spec locks the invariant: `dismiss.closest('a')` must be null.
Part of #285, address PR #288 review.

All under src/lib/components/chronik/:
- ChronikRow.svelte — single orchestrator for four variants (comment / for-you /
rollup / simple), discriminated via $derived. Outer <a> wraps avatar + body +
time; document title is a styled <span> (no nested anchors). Rollup shows
count badge + en-dash time range; for-you gets accent left border + @ marker
hidden below sm:.
- ChronikTimeline.svelte — buckets items by day using bucketByDay() and renders
Heute/Gestern/Diese Woche/Älter section headers with <span> trailing rule.
- ChronikFuerDichBox.svelte — unread mentions card with inbox-zero variant,
per-row Dismiss button (prevents bubbling, calls onMarkRead), aria-live count
badge, and a .fade-in class gated by prefers-reduced-motion.
- ChronikFilterPills.svelte — role=radiogroup with 5 pills, ArrowLeft/Right
keyboard navigation wrapping across the group, single tabstop via dynamic
tabindex.
- ChronikEmptyState.svelte — three variants (first-run / filter-empty /
inbox-zero) sharing a centered-column layout.
- ChronikErrorCard.svelte — warning card with retry button, optional custom
message override.
Verbs map to chronik_singleton_* / chronik_rollup_* per AuditKind so no ICU
pluralization is needed. Comment preview is a TODO placeholder (currently the
document title) pending a backend preview DTO follow-up.
All 40 unit tests green. No type-check or lint errors in these files.
