/* ==========================================================================
   Rehearse — landing page styles.
   Sibling of specscore.md's editorial register: paper and ink, hairlines,
   ~5 colours, no gradients, no rounded boxes, no decorative icons, no dark mode.
   Palette and type tokens are shared with specscore.md so the pages read as
   a family; Rehearse takes mark-red as its own accent (the prompter's ink).
