Constant FTL_CATALOGS 

pub const FTL_CATALOGS: &'static [(&'static str, &'static str, &'static str)];

The FTL catalogues that zeroclaw locales fetch / the daemon’s locales/fetch RPC can download, as (name, upstream-path-template, output-filename). {locale} is substituted per request. This is the single source of truth — a caller supplies only a catalog name matched against this table, never a path.
