/*
 * Inspection file preview modal layout.
 * Loaded after bundled scoped CSS (see App.razor) because MudFileUpload uses height:100% on its
 * input area and scoped styles do not apply to overlay child markup.
 *
 * MudOverlay with child content renders in-place. The shell fixed app bar stacks above
 * .mud-main-content, so top padding clears the header. Panel height must not use a raw 90vh
 * alone—that exceeds the padded flex area on tablets and clips the footer; cap height with
 * the same vertical budget as the content padding (custom property below).
