v0.10.0: hero polish

Hero-image polish release.

Changed

• The README hero's three blocks are now equidistant. The full hero refresh shipped inside v0.9.0 without a changelog entry: a redesigned one-to-many visual (one company template, extracted into a verified hexagonal Brand Profile core, fanning out into unlimited on-brand documents, with numbered extract / verify / generate steps), exported as the transparent assets/hero.webp the README embeds plus a white-flattened assets/hero.jpg, with assets/hero.svg as the editable source. This release balances that composition: the template page moved 30 px right, the core 45 px left, and the flow curves, flying brand particles and step labels were re-fit so the three blocks sit at even ~250 px gaps (pixel-measured on the render).
