Improve tile layout

It is hard to see the type of article of each tile.

For example, Haskell Interlude episodes are labelled “82 – Fraser Tweedale”.

We could add logos to each tile.

Start by locating the tile layout and the code or content that renders article titles, then inspect how article types such as Haskell Interlude are represented. Add a recognizable logo to each tile's article type, and verify that the tiles make those types easier to distinguish.
