/* Compact side-by-side layout shared by the Settlement cash screens:
     - Schedule Payment (SchedulePaymentForInvoices) -- PR 307810, now its only layout
     - Record Cash (RecordCashForInvoices) -- behind FEATURE_RECORD_CASH_COMPACT_LAYOUT, PBI 452918

   Global rather than component-scoped because two pages use it, and because several rules
   target markup that child components render (the <form> EditForm emits, Telerik's grid header).
   Scoped CSS needs ::deep for those; a global sheet matches them directly.

   The spfi- prefix is historical (Schedule Payment For Invoices). It is kept because
   wwwroot/js/schedulePaymentLayout.js writes --spfi-left and toggles .spfi-dragging, and the
   document viewer's stack (InvoiceGroupedDocuments.razor.css) uses the same prefix.

   Page markup contract:
     <div id="..." class="spfi-shell">          grid: form pane | handle | document pane
       <form class="spfi-form">                 the EditForm; display:contents
         .spfi-header  .spfi-pane.spfi-pane-left  .spfi-footer
       </form>
       .spfi-handle                             a SIBLING of the form, not a child
       .spfi-pane.spfi-pane-right               a SIBLING of the form, not a child
     </div>
   The document pane must stay outside the <form>: Telerik's PDF toolbar renders <button>s with
   no type attribute, and a typeless button inside a form defaults to type="submit". */

   spanning all three. */
