Subject: [PATCH 2/4] fix: Make dummy variables available

Cobalt's liquid has been changed to fail on missing variables.  This
could be made less strict in the future.

This means that every page reusing a layout needs the variables defined,
even if it is to `Nil`.

So added

 tl;dr: Rust is a safe systems-programming language. But besides its guaranteed safety, it also rivals C/C++ in speed for some datasets.
 Let me show you the tricks that Rust make Rust fast, which are possible but very hard to pull off in other languages.
 I will talk about agressive compile-time optimizations, zero-cost abstractions, fearless concurrency, and more.

 Text files are the single most important way we can communicate with computers. It's no coincidence that they are also the most important way to communicate with other human beings. What we can achieve with text files is invaluable: Write it once and refer to it whenever you want to get the message across in the future. Write a program (it's just text), save it and let the machine execute it whenever you like. Write another text file which contains the rules for the execution of your program and the computer runs your program exactly as you specified (`cron` files do that on Unix).
