• Redefined HTML and CSS for the processing screens on the backside of MiniLock.
• Revised human interface scripts to fit.
• Defined two sets of typography because I am indecisive about that right now. Toggle opensans-inconsolata or lucida-menlo on <body> to see each one.
• Introduced Inconsolata font so that we have a consistent monospaced typeface for all operating systems.
