/* Darstellung der Quick-Reference-Kapitel (Funk, Alphabet, Betonnung, KVR,
   Lichter, Knoten).

   Die Kapitel selbst stehen als Partials unter includes/reference/ und werden
   von zwei Ansichten gerendert: der geschuetzten Quick-Reference
   (pages/reference.php) und den oeffentlichen Wissensseiten
   (pages/wissen.php, /wissen/<slug>). Diese Datei traegt deshalb genau das
   CSS, das beide brauchen — das Seitenlayout der Quick-Reference (Raster,
   Sprungnavigation, Suchfeld) bleibt in pages/reference.php.

   Farben kommen ausschliesslich aus den CSS-Variablen von style.css, damit
   der Nachtmodus in beiden Ansichten greift. */

/* Sprungziel innerhalb des Funk-Kapitels: MAYDAY, SÉCURITÉ und PAN-PAN sind
   ueber ihre eigene ID anspringbar. */
