IBM Plex Sans (variable, 100–700) and IBM Plex Mono (400, 600) — latin subset, woff2, as served by Google Fonts. These are the locked brand fonts (see ../../../01-brand-system.md §4).

They are embedded (as data URIs) into every rendered report by pandoc --embed-resources, so a report renders identically on a machine that has never installed IBM Plex — which is the point: a client opening the PDF must see the brand, not a substituted system font.

Latin subset only, to keep reports small (~60 KB of font total). If a report ever needs non-latin glyphs, pull the full subset from fonts.google.com rather than hand-editing these.
