v9.11.0

v9.11.0 — 2026-07-03

Small release — header columns now precisely aligned with the exhibition table below via a shared colgroup

What changed

Each category's header row now uses the exact column mapping requested:

Cell	Content	Spans
1	▶ Category name	3 columns (under Exhibition/Date/City)
2	🗂 Exhibition count	1 column (under Cycle)
3	👥 Registration count	1 column (under Registrations)
4	(empty)	1 column (under Action)

Both the header's mini-table and the exhibition table (shown once opened) now share an identical <colgroup> defining the same 6 column widths. This is what makes the alignment precise rather than approximate — both tables compute their column widths from the same source, so the name/count cells in the closed header land exactly above the columns they represent once you open that category.

This keeps v9.10's fix (each category is still its own independent <div> with its own table — not one shared table for the whole page) while adding the real column structure you asked for, so a closed category reads as organised columns rather than loose text sitting next to other text.
