Sending Regular text and **bold text** reduced bold from the rich text composer's weight 700 to weight 600 in rendered messages. The global Markdown rule also applied with Settings → Beta → New design disabled, making emphasis difficult to distinguish in some fonts.
Restore .chat-markdown strong to weight 700 in both designs. This also restores bold in other surfaces using the shared Markdown renderer.

Diff0 shows every changed RGB pixel; DiffT uses a 16/255 maximum-channel threshold. Both amplify the absolute difference ×4. Static typography is shown with settled stills; paired stability frames have zero differing pixels.
Linux Chrome 156, DPR 2, 100% scale; desktop CSS viewport 1440×900 is captured by the preview service at 1280×800, narrow CSS viewport 390×844 at 780×1688. Inter Variable and Roboto Flex were verified loaded. CSS motion suppression was used because the preview tools do not expose reduced-motion emulation.
Visible differences: bold glyphs are heavier and slightly wider; the user bubble and its regular prefix move left by 1.5 CSS pixels; the preview table column shifts by 5.08 CSS pixels as bold-cell width changes. No wrapping or clipping.
Full evidence and reproducible fixture/driver · Fixture matrix.
Independent proof audit: all six pairs sufficient; C3 rebuilt at the exact head with zero pixel difference. Both isolated code reviewers returned MERGE.
