- docs/adr/003-chronik-unified-activity-feed.md: records the session-rollup
decision (LAG + 120-min gap), the dedupe deletion, the single-endpoint
composition, and the German-URL convention.
- frontend/messages/{de,en,es}.json: adds chronik_* keys for page title,
Für-dich box, filter pills, day headers, singleton/rollup verb variants
per kind, empty states, error card, Mehr-laden pagination, and the Bell
footer link retarget.
No pluralization via ICU match — separate singleton/rollup keys per verb,
per the Felix discussion (comment #3573).
Part of #285.
