/*
 * Home page.

 * Laid out like a product site's front page: one statement and its two
 * actions, then a section per thing people come for — each with a centred
 * headline, a sentence, links, and the thing itself — then what changed and
 * where else to go. The page borrows nothing of osu!lazer's look; only its
 * timing, in the entrance and in how links and entries answer the pointer.
