docs: pill-style section labels and flow tags, hero fills first viewport

- Section labels (Two Paths, Pricing, ...) restyled from mono //-prefix to Lato pill badges with glowing dot, matching the hero protocol badge
- Flow-step tags (Agent -> Server, Agent <-> Node, Base USDC, Automatic) restyled to rounded pill chips in Lato with a currentColor glow dot
- Hero now min-height calc(100vh - 56px) with flex centering so only the hero is visible on first load; Pricing starts below the fold
