/*
Theme Name: Ridge Board
Description: A theme for a site of roofing guides for homeowners, sorted into topics. The guides link to one another: the guide that links to the most others is read as the guide map, and the topics it lists group every other guide under a topic with its main guide; a guide is found by its address or, when the site gave it another address, by its title. The front page draws a house with a tiled roof beside the title, lists the topics in a numbered strip, then gives every topic a band of its own: its main guide with the opening of that guide, and every guide in the topic. A guide opens under a path line to its topic, reads in two columns with the guides of its topic beside it, and steps to the guide before and after it in its topic.
