The /zeitstrahl header sub-line counted the unfiltered timeline, so a
hidden layer (e.g. Letters off) still showed its entries in the totals
("1 Brief" with no letters on screen) — the documented D1 limitation.
Derive the meta from filteredTimeline so the range and letter/event
counts always match what is actually rendered. hasContent stays on the
full timeline so the filter bar and meta line still appear whenever the
archive has content.

Add the ten REQ-001…REQ-010 rows for the /zeitstrahl layer filter, each linked
to its implementation file(s) and test(s), all Done.

Playwright spec for /zeitstrahl: the primary journey (hide Letters → letter
cards vanish + trigger reports "1 aktiv" → reset restores) and a 375px axe pass
with the collapsible open in light and dark mode. Not skipped — #779 ships the
route. E2E is not wired into CI, so this runs locally only for now.

A static boundary gate (mirroring the project's no-`{@html}` greps) that reads
TimelineFilters.svelte and /zeitstrahl/+page.svelte and fails if either ever
reintroduces goto(, url.searchParams, api.GET, or fetch( — the filter must stay
presentation-only and fully client-side.

The route holds the three layer toggles in $state, binds them into
TimelineFilters, and derives a client-side filtered view of the SSR-loaded
timeline that it passes to TimelineView — no goto, no URL param, no extra
fetch. When the active toggles leave nothing visible it renders a calm
filtered-empty message plus a one-click reset below the still-open filter bar,
never a blank page and never the generic "no events" state. The meta-line keeps
counting the unfiltered timeline (D1 known limitation).

A dumb, client-side layer-filter bar for /zeitstrahl: three $bindable layer
toggles (Personal/Historical/Letters) in a fieldset/legend, a sticky
"Filter (N aktiv)" trigger driven by hiddenLayerCount, and a reset text button
shown only when a layer is off. Toggles mirror the SearchFilterBar undated-toggle
markup (aria-pressed, ✓ glyph, 44px touch target, semantic tokens). The
collapsible slide honours prefers-reduced-motion by zeroing its duration. No
goto, no fetch — the route owns the state and the filtered view.

Eight Paraglide keys for the /zeitstrahl layer filter — layer labels, the
fieldset legend, the sticky trigger (distinct timeline_filter_trigger and
timeline_filter_trigger_active({count}) so it never reads "Filter (0 aktiv)"),
the reset button, and the filtered-empty message — added to all three locales.
messages.spec asserts their presence and the {count} signature.

Pure helpers for the /zeitstrahl layer filter: isDefaultState and
hiddenLayerCount drive the "Filter (N active)" trigger, and filterTimeline
derives a client-side view that hides personal/historical/letter layers and
drops year bands left empty. Letters ride the Letters layer, HISTORICAL events
the Historical layer, and curated PERSONAL plus derived life-events the
Personal layer.
