/* ============================================================
   laundry — an ascii terminal theme for ghost
   ------------------------------------------------------------
   This is the development stylesheet. It is plain CSS (no
   imports / postcss features) so `assets/built/screen.css` is a
   byte-for-byte copy and the theme works with or without gulp.

   1.  Tokens + reset
   2.  CRT overlay
   3.  Intro (the washing machine)
   4.  Tag rails + wires
   5.  Open / close choreography
   6.  Archive (the posts grid)
   7.  Post cards
   8.  Single post / page
   9.  Author + error templates
   10. Site chrome (nav, footer)
   11. Responsive
   ============================================================ */
