Constant DISPLAY_ROWS 

pub const DISPLAY_ROWS: &[OptionSpec];

What: The rows CONFIG_DISPLAY_OPTIONS adds before the type rows (config.c:111-117). Why: Git appends CONFIG_TYPE_OPTIONS to this group, so users list both in that order.

In TS you’d write (pseudocode):

export const DISPLAY_ROWS = [row(UNREAD, 'z', 'null', 'none', true), /* ... */] as const;
