Did a set of site updates for Greek vocabulary (Chapter 2, and the review of Ch 2 in Chapter 3). In the process, I re-learned a lesson that I've had to learn before, and haven't documented, so here it is:

The Greek site is really designed to be built en masse using Masher batch files; there's a batch file for each of the main sections (Grammar, Vocab, etc.). Key info for building each exercise is in the Batch file, rather than the individual Masher files in each of the chapter folders. Therefore, if you want to build an individual unit or an exercise from a unit, this is what you need to do:

• Load the Masher file for that unit/chapter.
• Load the Masher Batch file for that section (e.g. vocab). This loads extra info into the Masher interface, required when the exercise is being built.
• Build the unit or chapter.

When you're done, check the exercises look right on the server. Symptoms of borked settings include a green background in drag-drop cards in matching exercises, or a missing background image (replaced by plain green).
