   Nếp on a computer (1000 px and up, the default look). index.html loads this file with media="(min-width: 1000px)"
   and every rule is inside the same query again, so a phone never sees any of it. pc.js moves the pieces into place:
   .shell.pc = a sidebar (.pc-side: Nếp dressed, the top bar, the sections) and the page; on Hôm nay the hello, the
   platform as wide as the page, the line under it and a rail (.pc-rail: the line in small, this week, the cards due).
   The feel: big bold headings, room to breathe, white cards on hanji, pill buttons, the season over the whole page.
   Tokens are pop.css's; dark keys off html[data-theme="dark"] like everywhere else.
