/* The app guides (/guides/<app>/) and the guides list (/guides/). One light design for every guide; each app brings its
   accents as a few tokens in its own <style> (see kit/template/guide/index.html and kit/GUIDE.md):

     --app        the app's dark colour: the hero band, headings' marks, links      (Murmur: dusk purple)
     --app-2      a second stop for the hero gradient                                (Murmur: mauve)
     --app-3      a third, lighter stop at the bottom of the hero                    (Murmur: dusk peach)
     --app-ink    text on the hero band
     --c1 … --c8  the app's section colours (Murmur: its six tab colours), used as chips and section marks

   Paper, ink, type and layout are fixed here so every guide reads the same. Lexend is shared with the homepage. */
