The bare "· {count}" spans in both the same-year and cross-year headers
announced as "· 2" with no context. Each now pairs the aria-hidden visible
count with an sr-only "{count} Briefe" via a new Paraglide key
(timeline_cluster_letter_count, present in de/en/es). Fixes review
finding #6 (count half).

The cross-year card header emitted a bare aria-hidden ✉ with no sr-only
label, unlike the same-year header and LetterCard — a screen-reader user
heard only the title with no cue that this is a letter group. It now uses
the shared GlyphLabel (✉ + sr-only "Brief"). Fixes review finding #6
(glyph half).

A curated event with linked letters renders as one contained card: the
event is the header (accent glyph, title, date · provenance, count, and a
curator edit link), its letters sit inside as compact .lcard.ev cards. The
first CLUSTER_PREVIEW (5) show, then a keyboard-operable show-more/less
toggle reveals the rest. A cross-year card (no event prop) gets a plain
'✉ title' text header with no edit link. Titles render through default
{...} escaping. Adds timeline_bucket_show_more/less keys to de/en/es.
