/* hushpix.app. The look of the author's blog (blog.lufficc.com): paper and grain, a serif for what is read first, a
   mono for labels, hairlines. The layout is an app's: a wide page, the words beside the phone, each section's words
   beside its drawing; reading pages (questions, policy) keep the blog's one narrow column. Behind the hero, a page of
   a screenshot with its private words covered (tools/make_texture.py); the accent is the app's cover green. */
