feat(web/panettone): Add initial styles r/1442

Take an initial crack at styling most of the Panettone application,
taking inspiration from the styles from todo.tvl.fyi and tvl.fyi itself.
This uses the LASS CSS library, after a brief attempt at using css-lite
which I ended up not going with because I don't like the library's
design very much, and also it's not compatible with sbcl's (safety
3) (some macroexpansions SETQ undeclared variables).
