src/uix/README.md (485 L, Spanish) translated to English as the book's
opening chapter. Two already-decided reconciliations applied in passing:
the 'authoritative GUIA' pointer now reflects its historical status
(phase-6 decision) and the frozen 2026-05-17 migration status became the
timeless statement (every component ships an eidos wrapper; inventory =
tree + component:audit). Thin stub at the old path; docs/README entry,
strata table and reading order repointed. docs:check 0 errors.
