/* =========================================================
   Calendar (pure CSS, no JavaScript)
   ---------------------------------------------------------
   Each month is an ordinary top-level org headline — no HTML
   needed for the structure at all:

     * July 2026
     :PROPERTIES:
     :CUSTOM_ID: cal-2026-07
     :HTML_CONTAINER_CLASS: cal-panel
     :END:

     [[#cal-2026-08][Next month →]]

     #+ATTR_HTML: :class cal-events
     - Jul 15 (Tue) :: *Chapter Meeting* --- 6:30 PM, Community Center

   :CUSTOM_ID: gives the headline a stable anchor id. Org's
   :HTML_CONTAINER_CLASS: property adds "cal-panel" to the
   <div> org already wraps around every headline, so no manual
   markup is required. Prev/Next are just ordinary org links
   pointing at those ids. The event list is a normal org
   description list (`term :: description`), tagged with the
   cal-events class via #+ATTR_HTML.

   HOW THE SHOW/HIDE WORKS
   CSS :target shows whichever month's link was clicked.
   :has() supplies the default (show the first month) whenever
   nothing is targeted yet — so there's no "checked" attribute
   or per-month rule to maintain, and no limit on how many
   months you can add. This relies on :has(), which is
   supported in all current major browsers.

   HOW TO ADD A MONTH
   Add another headline like the one above, in order, with a
   unique CUSTOM_ID. Update the neighboring months' Prev/Next
   links to point to it.

   HOW TO ADD AN EVENT
   Add another `term :: description` line to that month's list.
   Nothing else needs to change.
