The function has a single in-source call site (TimelineDensityFilter)
but is exported so timeline.spec.ts can pin its boundary semantics
without rendering the orchestrator. Note that explicitly so future
readers don't treat the export as a public API contract.

Previously a 5xx, network blip, or JSON parse error all collapsed
into the same silent "no buckets" rendering. The widget still
degrades gracefully — failure should not block the document list —
but operators and Sentry now see the failure in browser devtools
instead of having to reverse-engineer a missing chart.

Tablet (640–1024px) is exactly the iPad audience for transcribers.
At 240 monthly bars on an 800px column the bars fall to ~3.3px wide,
well below the 44×44 touch-target floor. Bumps the visibility class
from hidden sm:block to hidden lg:block and matches the page.ts
matchMedia gate to (min-width: 1024px). Closes Leonie's tablet
touch-target finding.

Replaces the discrete zoom-in button with a Graylog-style drag-to-zoom
range selector and adds X/Y axis labels so the chart is readable.
Drag interaction
- Pointerdown on a bar attaches document-level pointermove/pointerup/
pointercancel listeners; pointermove maps clientX to a bar index via
the row's bounding rect, so the mint-bordered window expands smoothly
even when the cursor leaves the bar or the chart entirely.
- pointerup commits filter + zoom atomically. Same-bar release on a
year bar (year-aggregated mode) zooms into that year's months;
same-bar release on a month bar emits filter-only.
- setPointerCapture removed — it was suppressing pointerenter on
sibling bars and preventing the drag window from expanding.
- Bar buttons are now h-full so the entire 80 px column is the hit
target, not just the visible bar height.
Axis labels
- Y-axis: max-count and 0 labels left of the bar area.
- X-axis: tickIndicesFor() picks decadal years for long ranges, evenly
spaced months for short year-zoom views, January boundaries for
multi-year month ranges. formatTickLabel() drops the year when the
visible range is a single year so 12-month zooms read "Jan Feb Mär…".

Adds a zoom action that narrows the visible timeline range to the current
selection so the user can drill from year-level back into month-level
density. Zoom state lives in the URL (zoomFrom / zoomTo) so it survives
reload and is shareable.
- New `clipBucketsToRange(buckets, from, to)` helper applied before the
>240-month year-aggregate decision, so a zoomed window flips back to
month bars automatically when the clip narrows the range enough.
- `TimelineDensityFilter` gains `zoomFrom`, `zoomTo`, and `onzoomchange`
props. Zoom button shown only when a selection exists and we aren't
already zoomed; reset-zoom shown only when zoomed. Both placed in a
shared right-edge action cluster alongside the × clear button.
- `+page.ts` reads zoomFrom/zoomTo from the URL and forwards them as
props. `+page.svelte` extends FilterSnapshot + buildSearchParams, and
triggerSearch accepts an optional zoom override so the onzoomchange
callback can write the new pair (or clear them) atomically.
- 7 new component tests + 2 new page-integration tests cover the
visibility rules and URL writes.
- 4 new unit tests for `clipBucketsToRange`.
- 3 new i18n keys (zoom in / zoom reset / drag aria-live) across de/en/es.

The +page.ts client-side load now forwards the active /documents URL
filters (q, senderId, receiverId, tag, tagQ, status, tagOp) to
/api/documents/density so the bars recompute when the user narrows the
search. Date bounds (from/to) are deliberately omitted — the chart is
the surface for picking those.
- New `DensityFilters` type and `buildDensityUrl(filters)` helper.
- `fetchDensity` accepts a filter snapshot (defaulting to {} for
back-compat in tests).
- 6 new unit tests cover URL building, multi-tag repetition, AND/OR
forwarding, the explicit-no-from/to invariant, and filter-aware fetch.
- Generated API types refreshed against the new backend signature.

Surfaced during proofshot: the production archive spans 1873 → 2023
(≈1809 month bars). With flex-1 + gap-px on a 1280 px container, every
pixel was consumed by gaps and bars rendered at 0 px width — visible as
"empty box, no bars".
Fix:
- Add aggregateToYears(buckets) that sums month counts per year and
returns YYYY-keyed entries.
- Add selectionBoundaryFrom/To that handle both YYYY and YYYY-MM labels
(Jan 1 → Dec 31 for years, first → last day for months).
- Component switches to year granularity when the gap-filled month
sequence exceeds 240 entries (~20 years), keeping each bar clickable.
- Drop the gap-px between bars and add min-w-px so sub-pixel rounding
still leaves something visible.
5 new tests cover aggregation, boundary helpers, and the component-level
year-mode + click behaviour.

The density data is fetched only on tablet/desktop (sm:+ breakpoint) and
when ?view=calendar is not set — mobile users and the future calendar view
(#386) skip the request entirely. Lives in +page.ts (client-side) so the
matchMedia gate can run in the browser; +page.server.ts continues to handle
the document search.
Non-ok responses and network failures degrade to an empty bucket list
rather than throwing, so the document list keeps rendering.
5 unit tests cover the gating + graceful degradation paths.

Pure utilities backing the TimelineDensityFilter component:
- monthBoundaryFrom/To convert YYYY-MM into LocalDate strings the existing
/api/documents/search accepts (first/last day of the month).
- buildMonthSequence enumerates months between minDate and maxDate, crossing
year boundaries.
- fillDensityGaps merges sparse backend buckets with the full month sequence,
producing zero-count entries for months that the API omitted.
14 unit tests cover leap years, year boundaries, null inputs, and out-of-order
buckets.
