Added get_qes_master() for harmonized merged datasets across QES studies.
Added merge quality controls: within-year respondent de-duplication and all-empty-row removal.
Added broader harmonization for age, age group, education, turnout, vote choice, and weights.
Renamed opaque legacy merged variables (e.g., q10, q16, voteprec) to readable names and added transparent old-to-new mapping via variable_name_map.
Added variable-name mapping sidecar output (*_variable_name_map.csv) when saving/building merged datasets.
Improved codebook workflows with compact/wide/long layouts and value-label extraction helpers.
Updated researcher website use-case figures with clearer year-axis labeling, dynamic y-axis bounds, and expandable full code blocks for reproducibility.
Added researcher website content with merged-dataset documentation, study citations, and analysis examples.
qesR 0.4.3
Added get_question(..., full = TRUE) support for richer question-text recovery.
Improved codebook metadata parsing and handling of support files.
qesR 0.4.2
Expanded QES catalog entries and Dataverse file selection behavior.
