   web.css - the trainer on a website (laptop, PC, tablet, phone)
   Loaded after style.css and design.css. Every class added for the web
   starts with "w-" so it never collides with the app's own classes.
   Layout from 1100 px: tab bar becomes a left column, content stays one
   readable column, and from 1280 px a right column carries the app card
   and one ad space.
