# ---------------------------------------------------------------------------
# Trailing-slash normalization (uscogdata #3 follow-up).
#
# EVERY consumer builds paths by concatenation: paste0(url, "manifest.json")
# (manifest.R), paste0(url, e$path) (mirror.R), and the parquet glob in
# views.R. mirror.R:104 even comments 'url ends in "/"' -- an assumption the
# package documents and relies on but never enforced.
#
# A URL missing its trailing slash therefore fails SILENTLY and confusingly:
#   HTTPS -> ".../downloadmanifest.json" -> the host answers with an HTML 404
#            page -> the jsonlite lexical error that issue #3 reported;
#   local -> ".../corpusdata/long/**/*.parquet" -> DuckDB "No files found".
# Neither message points at the real cause. Normalize once, at resolution.
