/* Hrdware — every colour and style in one place.
   Follows "Hrdware visual identity & digital design standards" v1.0 (8 Nov 2026).
   Change the brand here: the homepage, its drawings and the app only use these tokens and classes.
   Section 1 (tokens) is global. Sections 2-5 are the homepage, scoped to <body class="hp"> so they
   never touch the app, which imports this file for its tokens (app/src/styles.css).
