 *  SocratesOne shared shell
 *
 *  The common theme behind index.html, investors.html, and privacy.html:
 *  colour tokens, the framed panel, titlebar, footer, long-form
 *  typography, and the form controls all three pages share.
 *
 *  Page-specific rules stay inline in the page that needs them — the
 *  homepage Q&A engine, the investor status table, and so on. Anything
 *  that must look identical across the three pages belongs here.
