Changes in version 0.1.0 (2026-10-28)                  

  - First release.
  - One frame for titles, legends, panels and captions around any ggplot
    (theme_hairline()), with the type scale, spacing and line widths of
    the shared design tokens.
  - Nineteen charts, from bars and time series to Kaplan-Meier, forest,
    Sankey and PRISMA diagrams.
  - hl_study() with endpoints for cohort description, group comparison,
    effects, survival and change over time; each returns a figure, a
    table, values and a sentence.
  - Brands in the 'brand.yml' format, entity colours pinned to names,
    colour-vision checked palettes, light and dark schemes.
  - hl_save() for PDF, PNG, TIFF, SVG and interactive HTML; files are
    named by the figure and carry no timestamps.
  - Output matches the 'hairline' Python package.
