/*
 * ITFlow - DataTables for the client portal.
 *
 * The agent side initialises DataTables from js/app.js, which the portal cannot
 * load: app.js calls TinyMCE, Tom Select, Flatpickr and IMask unconditionally
 * and none of them exist here. This is the portal's own one-liner rather than a
 * shared extraction, because unlike the phone-input logic there is no real
 * behaviour to keep in step - just a constructor.
 *
 * A separate file, not an inline <script>, because portal pages send
 * Content-Security-Policy: default-src 'self', which blocks inline script.
