/* Case study template
 *
 * Shared by every case study rendered from the CMS. The five hand-built
 * pages under results/case-studies/ do NOT use this file: each of those
 * carries its own inline stylesheet and its own palette, and they are left
 * exactly as they are.
 *
 * The structure here is baby-safety-launch's, with its palette lifted into
 * variables so a case study can pick a theme without a new stylesheet.
 *
 * Themes: amber, rose, green, teal, burnt -- matching the five published
 * pages. A case study may also supply its own two colours, in which case
 * the renderer writes --accent and --ground inline on .cs-page.
