v0.71.4

Changed

• Faster Settings navigation: switching between settings pages now swaps only the content area instead of re-rendering the whole screen. The side menu stays put and pages change instantly — without a reload, an extra authentication round-trip, or a slide animation. Browser back/forward between settings pages is just as fast.
• Consistent Settings headings: section headings are now larger than the cards they group, fixing an inverted type hierarchy where group titles appeared smaller than the content beneath them.
