++## 4.84.0 — 2026-11-01
++
++- **A page with no stylesheet of its own reads in the network's type.**
++  - `shell.page` set no font. On five sites (Events, Run, AI, Bot, Games), `/updates` loads no stylesheet, and its text
++    fell back to the browser's Times New Roman.
++  - The head's reserve style now gives the body `var(--ov-font, 'Inter', system sans)` through `:where(body)`. At zero
++    specificity, any site's own body rule wins, so nothing changes on a page that already sets its font.

  ## 4.83.0 — 2026-11-01
  
  - **Status words read on light themes.**
