/* reader.css — the first-chapter reading surface.
   Loaded only by /where-the-heathen-rage/first-chapter/.

   Everything here is built from the tokens already in site.css. The one thing
   this page does that no other page does is get out of the way: while somebody
   is reading a novel, the furniture should be the book's, not the website's. */

/* -------------------------------------------------------------- always paper
   The rest of the site follows the reader's OS, and should: it is a website.
   This page is a book. A novel printed on white stock should not arrive as pale
   text on near-black because somebody's Mac is set to dark, and a reader who
   turns dark mode on system-wide has said something about their inbox, not
   about how they want to be handed the opening of a story.

   So the light values are re-declared on the reading page and nothing else
   changes. Every token site.css defines is repeated here, not only the ones the
   prose happens to use -- the site header and footer render on this page too,
   and a half-pinned palette is how you get light chrome over a dark panel. */
