Catalan is the primary language and is now served at the bare domain (/),
with the previous /ca/ subdirectory removed entirely. Spanish remains at
/es/. The selector landing page is no longer needed: visiting / shows the
full Catalan article directly.
Introduce bilingual site routing with Catalan as primary language and
x-default, plus Spanish as the alternate. Each page declares its own
canonical, full hreflang block, locale and locale:alternate, and a
language-specific og:image. A top-right selector (CA | ES) lives in
every <header> with aria-current set on the active language.
- /ca/index.html: Catalan translation of the full editorial (title,
meta, hero, six body sections, chart titles/desc/figcaption, footer).
- /es/index.html: previous Spanish content moved under /es/, with
updated canonical and metadata.
- og-image-ca.jpg and og-image-es.jpg: separate 1200x630 social images.
- og-image.jpg removed (no longer cross-language).
- sitemap.xml rewritten to list both URLs with xhtml:link hreflang
annotations and x-default.
- README and CHANGELOG updated to document the new structure.
