   ListingPrep — global tool-chrome styles.
   Mobile-first, vanilla CSS, system font stack only.
   Scope: the 3 tool pages (Resize / Mockup / PDF Maker).
   Tokens here are the legacy navy palette; the new public-identity
   pages (home + legal + privacy + terms + thanks) load
   /css/listingprep.css on top, which adds --color-brand (teal).
   Bleu/teal seam is acknowledged transition debt — to close at the

/* ============================================
   Drive collision modal — shared chrome.

   Migrated from /css/pdf-maker.css in Chantier α palier 1. Now consumed
   by Resize + Mockup + PDF Maker collision modals via window.WallArtDrive.
   preflightFileCollision returns the data; each tool keeps its own
   .drive-collision-modal element in HTML and its own openDriveCollisionModal
   handler in JS, but the visual rendering is unified through this CSS.

   Layout per row: filename + path label on top, Skip / Save-as radio
   choice below. Single-conflict cases still use the modal (uniform UI
   with multi-conflict cases). For batch-global usage (Resize multi-format,
   Mockup multi-mockup, PDF Maker unlinked), the modal can show N rows
   with grouped sections per artwork — the row CSS is unchanged.
