/* railcast.de/technik — Ergänzung zu /style.css.
   Hier stehen nur die Bausteine, die es sonst nirgends auf der Site gibt:
   Faktenkacheln, Callouts, ASCII-Diagramme, Glossar. Farben, Fonts, Dark/Light
   und der Skip-Link kommen aus /style.css; deshalb wird die zuerst geladen.
   Klassennamen bewusst mit doc-/fact- präfigiert, damit sie nicht mit den
   Landing-Klassen (.kpi, .footer, .note) kollidieren. */
