One shared dataset — the same realistic Norwegian club årshjul (28 items harvested from Nidelv IL, Drag IL and the NDF/NIF wheel) that drives the radial wheel — presented as contender B of three: an honest paged month navigator. The deck unit is a MONTH, never a category; categories are group headings inside the card. The same data also drives the radial wheel lens and a span-grid lens (their own bake-off cards).
What this contender must prove: focus and drill-down (and mobile). One complete month card holds ALL of the month’s items with full details — timing including day-of-month, owner role, frist badges on confirmed deadlines and notes — with no fixed card height and no title truncation. Neighbor peeks show only the adjacent month’s name and direction; navigation wraps December→January (and back) with an explicit year-seam marker, because an årshjul is an annual cycle. A persistent 12-cell month index doubles as minimap and density strip: short labels, selected state, current-month marker and a per-month density bar (the count lives in each cell’s accessible name). Clicking any cell jumps directly — no animation through intervening months.
Accessibility model: every navigation control is a real button (peeks keep a 44 px hit target even when visually small); ArrowLeft/ArrowRight page the deck wherever focus sits inside it; focus stays on the initiating control after navigation; and a polite live region announces the new month and its activity count. Motion is a 200 ms 2D slide with a slight fade — reduced motion swaps instantly; swiping has a horizontal-intent threshold and never intercepts scrolling that starts inside event content. Density is never color alone — each index cell carries a visible bar plus its count in the accessible name.
Same dataset as the radial wheel (contender A) · landscape note: Årshjulet (NIF) — NIF’s own share view is a month-deck carousel; this contender rebuilds that idea with span semantics, full details on one card and an a11y-first interaction model.
