/* =========================================================================
   Ludic Media Studio — audience concept pages (events, L&D, change)
   Loaded by for-events.html, for-learning.html and for-change.html ONLY,
   after sections.css, via each page's `extra_css`.

   The pages are built in the Visual Scribing v2 language: the `vx-` classes
   come from sections.css, and this file adds the `ax-` components that
   page did not need — a filterable journey, tabs, sequences, a take-home
   ticket, a change curve, a hub, a measurement panel.

   Same rules as every stylesheet in the build: no ID selectors, only the
   documented breakpoints (36 / 48 / 64 / 80rem), only the measured colour
   pairs (black, white, yellow, cream, dark grey), never white on yellow.
   Every hidden state hangs off a class the script adds, so with no script
   everything on these pages is visible.
