Add custom font to writefreely self hosted blog

This is fairly simple but worth noting.

1. Find a font, files will either be hosted or downloadable.
2. If requiring download, then download the files (e.g. font.woff, font.woff2) and upload to the /static/fonts subdirectory of the main writefreely directory e.g. /var/www/wfsite.com/static/fonts using e.g. scp
   1. scp ~/Downloads/murmure-main/fonts/webfonts/LeMurmure-Regular.* user@server.com:/home/user/
   2. ssh user@server.com
   3. sudo mv LeMurmure-Regular.* /var/www/wfsite.com/static/fonts
3. writefreely > admin > customise
4. In the "Custom CSS" box add a CSS @font-face rule to define the location of the font, followed by CSS selectors specifying the elements which should use the custom font (for hosted fonts, use regular absolute URLs):

@font-face {
    font-family: "lemurmure-regular";
    src: url("/fonts/LeMurmure-Regular.woff2") format("woff2"),
         url("/fonts/LeMurmure-Regular.woff") format("woff");
    font-weight: normal;
    font-style: normal;
}
header h1 {
    font-family: lemurmure-regular;
    font-size: 100px;
    font-feature-settings: "ss02";
}
