Strip a leading English date prefix from a BLUF sentence so the synthesised title doesn't open with a literal date. Returns the input unchanged when no pattern matches.
Guard: if stripping would leave a sentence that starts with a verb (e.g. Friday 8 May 2026 marks … → marks …), we keep the prefix and let the downstream truncate handle it — a slightly date-leaky title beats a grammatically broken one. Pure function — exported for tests.
