/* Flag brand faces — the ONE font sheet. Load this and nothing else.
 *
 * Elcano ships exactly two typefaces, everywhere, in every product:
 *
 *   Nebula Sans  — UI, body, headings          (--font-brand)
 *   Hack         — code, logs, tabular output  (--font-code-brand)
 *
 * Both are freely redistributable, which is why there is only one sheet now.
 * The old tiering (Dubai for internal-only tools, IBM Plex for public repos)
 * existed solely because Dubai was proprietary and could not ship in a repo
 * carrying an outbound licence. Neither of these faces has that problem, so
 * every product — MIT, BSL 1.1, or internal — loads this same file.

/* Brand-face selection. design-tokens.css reads these three variables and
 * never names a family itself, so this assignment is what binds the whole
 * token layer to Nebula Sans and Hack — independent of stylesheet import
 * order, because the token sheet only ever reads them.
 *
 * --font-code-brand and --font-code-ui-brand are both Hack on purpose. They
 * used to differ (Share Tech Mono for code, VT323 for the retro task-tracker
 * chrome); the two-face retro language is gone and one mono now serves both.
 * The variables stay so product CSS that reads --font-code-ui keeps working.
