 * The brand asset is a 205x91 wordmark WITH a tagline, and no square
 * monogram has been supplied. Fitting the whole thing into a 28px circle
 * renders the tagline as ~2px of unreadable microtext, which reads as a
 * smudge rather than a logo.
 *
 * So crop to the primary mark: `cover` + `object-position: top` on a box
 * whose ratio matches the "MSI" lettering alone (roughly the top 78% of
 * the source, 205x71), which drops the tagline and lets the letterforms
 * use the full width. Swap this back to a plain `contain` if a square
 * monogram is ever supplied — see the note in CLAUDE.md.
