/*
Purpose: Mullusi public website visual system and responsive layout.
Governance scope: public-facing structure, route clarity, canvas substrate layering, and data-rendered card surfaces.
Dependencies: Newsreader and Space Mono web fonts, assets/app.js canvas/runtime hooks, and static JSON render targets.
Invariants: content remains legible above the substrate, mobile layouts do not overlap, and cards keep bounded surfaces.
