- Editorial chartSwitch: drop the per-button isFirst flag and put the divider on the parent via "& > button + button { borderLeft }"; chartSwitchButton(active) now matches bold/modern's signature
- Drop the empty company: {} entries in bold/modern and the wrapper span around the company name; the parent brand row already styles it
- Editorial styles factory: keep the (tokens, isDark) signature for cross-theme uniformity but acknowledge the unused isDark with a void-statement instead of an underscore prefix
