All visible text, lists, image refs, and CTAs for the home page now live
in en/index.md and es/index.md as a typed `sections:` frontmatter array.
HomePage.astro is reduced to a thin router; each section type is rendered
by a dedicated component in src/components/home/. Adds .no-balance utility
class to suppress text-wrap: balance on the commitments heading.
