 * Third design (2026-09-21): dark, editorial, the product shown working. Ink navy as the GROUND
 * (the app's refresh made it a surface), Instrument Serif for headlines, Inter for everything
 * else, teal #007b82 as the one accent, rust for the missed-call moment. Light bands alternate
 * with dark ones so a page breathes.
