Módulo:Fuentes del libro

La documentación para este módulo puede ser creada en Módulo:Fuentes del libro/doc

-- Módulo:Fuentes del libro
-- Renders a "Buscar este libro" block with three sources below {{Ficha de libro}}:
--   • Casa del Libro (Awin-tracked affiliate, disclosed)
--   • Google Libros  (free; uses isbn: query prefix when querying by ISBN)
--   • WorldCat       (free)
--
-- Args (read from parent template if invoked via wrapper, else from frame):
--   isbn   = ISBN (preferred lookup key; specific edition)
--   titulo = book title (fallback when isbn is empty; uses {{PAGENAME}} if both blank)
--
-- Renders as a <table class="infobox"> so it visually matches the {{Ficha de libro}}
-- above it (same border, same background, same 100%%-width mobile responsive rule).
