c1. Q Nuxt Layer Integration

The www.qpoint.io site has been consuming local copies of shared components (Hero, BlogCard, Quote, Step, Grid, BigPoint, Check, SectionHeadline, StepWrapper, Point, BlogAuthor, FAQ) that were already extracted into the q-nuxt-layer. The site needs to fully adopt the layer — delete local duplicates, update all content references to use Prose/Layout prefixed names, simplify CSS and tailwind config, verify the build, and deploy.

This work is already ~90% complete on the design-integration branch.

Create a plan, ask any clarifying questions, suggest patterns I may not be considering.
