/*
 * Digital Forensics shared interface
 * forensics-style.css
 *
 * Canonical stylesheet for EthanJHulbert.org/digital-forensics/.
 * Tool pages should progressively normalize their markup to the .forensics-* classes below.
 *
 * Page convention:
 *   body.forensics-page
 *   main.forensics-main
 *   header.forensics-header
 *   .forensics-upload
 *   .forensics-workspace.forensics-requires-file
 *   section.forensics-section
 *   section.forensics-about   (always visible, after export)
 *   footer.forensics-footer   (always last)
 *
 * File-state convention:
 *   Before a file is loaded, keep body WITHOUT .forensics-has-file.
 *   Add .forensics-has-file after a successful load.
 *   Anything marked .forensics-requires-file stays hidden until then.
