  <h1>RAM, CPU and terminal per user</h1>
  <p>
    Each value is taken from the first place that sets it: the user (this page),
    their team (<a href="{{ base_url }}admin#/groups">Admin → Groups</a> → the team → properties
    <code>memory_max</code> / <code>cpu_quota</code>), then <code>resource_limits</code> in
    <code>hub_settings.json</code>. <b>Terminal off</b> removes New → Terminal for that user;
    <code>terminals_enabled: false</code> in <code>hub_settings.json</code> turns it off for everyone.
    Saving a user replaces all three of their settings. Changes apply on the user's next server start.
