/// Cross-platform tests for the OpenAI dashboard text parser.

/// The dashboard renders reset countdowns like "Resets Wednesday at 3pm". The parser
/// converts a textual weekday into the next occurrence of that weekday so it can be
/// formatted into a concrete `Date`. These tests pin down full-weekday-name coverage
/// because the underlying regex previously missed "Wednesday" and "Saturday" (their
/// abbreviations were not long enough to combine with the optional "day" suffix).
