/* Project VS styles.
   Design: NotebookLM's layout with an Apple-like finish: one consistent set of colors, type sizes,
   corner radii, shadows and motion (the tokens on :root). Use the tokens instead of new values,
   so every screen keeps feeling like the same product.

   Two layouts, switched at 860px:
     Computer (861px and up): expansive. Grids, side-by-side panels, search/sort, full toolbar.
     Phone (860px and below): practical. Grouped lists, one thing at a time, bottom tabs, big "+".
   Helpers: .wide-only shows only on computers, .phone-only only on phones. */
