/* rainn.works — shared chrome for every page. Implemented from the claude.ai/design project "rainn.works" (bff857ab-daf4-45e0-ba95-3e5578cb12ec). The design ran on the dc runtime, which pulls React and Babel from unpkg before anything paints; this site is the same pages as plain HTML and CSS, with a little vanilla JS where a page has a live demo. The design had desktop widths only — the phone layout under the media queries at the bottom is ours. Each app page sets its own palette on : --accent the app colour --well the app's dark background --pale text on the well (rgb triplet, so alphas can be derived) */ :root { --paper: #F5F4F1; --ink: #151513;
