   script (mtoggle) shows only the ones relevant to the selected type. #}
{% macro type_fields(config={}) %}

{# What each type checks, shown under the row for the selected type. #}
<p class="field-hint mfield" data-types="icmp" style="grid-column:1/-1;margin:0;">
  <strong>Ping</strong> sends an ICMP echo to the target, a hostname or IP. Up when it answers; the round trip is the latency.</p>
<p class="field-hint mfield" data-types="tcp" style="grid-column:1/-1;margin:0;">
  <strong>TCP</strong> opens a connection to the target on the port below (22 for SSH, 443 for HTTPS, …). Up when the port accepts; the connect time is the latency. Nothing is sent.</p>
<p class="field-hint mfield" data-types="http" style="grid-column:1/-1;margin:0;">
  <strong>HTTP</strong> requests the target URL (http:// or https://). Up when the status matches, and the page contains the text below if you set one. For https, the certificate's expiry is tracked too.</p>
<p class="field-hint mfield" data-types="dns" style="grid-column:1/-1;margin:0;">
  <strong>DNS</strong> looks the target name up (google.com, nas.lan, …). Up when it resolves, and to the expected IP if you set one. With no resolver it asks the way Steward's container does (its resolv.conf, so usually your local DNS) and records no response time; name a resolver (1.1.1.1, your router, …) to ask that server directly and time its answer.</p>
