    KOREAN TYPOGRAPHY
    Reference: modern Korean studio sites (Studio fnt, Plus-X, Hi-Phen, etc.)

    Latin drop-cap / italic conventions, and pull tracking in. Hangul is
    denser per character than Latin, so we also scale body text down a hair
    and tighten line-height to prevent the page from feeling "loose."
