   Media Hub — /media-hub
   AINS Summit Austin Press & Media Kit.
   A modular, deep-linkable hub: sticky section rail on the
   left, anchored content sections on the right. Each section
   carries an id + a "copy link" control so any one section can
   be shared on its own (e.g. /media-hub#founder-bios).
