/* helm — shared site styles
 *
 * Source of truth for chrome (vars, reset, body, container, header, footer,
 * buttons). Page-specific styles stay inline in each page's <style> block.
 *
 * Width convention:
 *   .container — 960px max, used on every page (keeps header + footer consistent)
 *   .narrow    — 720px max-width wrapper for prose sections (used inside .container
 *                for legal pages and the prose sections on index)
