/* vfslab.css · Direction B "Pro Mac app" (docs/frontend/design-v2)
   One stylesheet, no framework, no build step, CSP-safe (no inline style needed).
   The design's stylesheet with the app shell (layout.html), the shell
   components (menus, dialogs, toasts, drawer), the backend leftovers
   (wizard steps, Made with, help, tour) and the old utility hooks appended
   as sections 13-16.

   Layout, by width
     >= 1200  sidebar | work | inspector (summary always on top, tabs below; can fold to a rail)
     768-1199 icon rail | work, summary as a toolbar row; inspector is a right-side sheet
     < 768    nav bar + slim status bar (sticky), work, bottom tab bar; inspector is a bottom sheet

   Sections
     1 fonts   2 tokens   3 base   4 shell   5 sidebar + bars   6 summary   7 inspector + sheets
     8 controls   9 content blocks   10 screens   11 motion   12 reduced motion
     13 app shell (layout.html)   14 shell components   15 backend leftovers   16 utilities and old hooks
