v0.71.31

Changed

• App-wide typography now follows one responsive semantic hierarchy: mobile and desktop use fixed hero, page, section, card, body, secondary, caption, and micro roles instead of drifting module-specific sizes. Oversized mobile headings were reduced, readable supporting text now starts at 14px, prose and inputs stay at 16px, document and split-expense headings are consistent, and Settings leaf pages show one clear primary title.
