  /*
    Feature post-it — the categorical card in a 3-column grid. Always opens with
    a 60px round ink-bordered icon containing a single Shrikhand character. The
    icon is the visual signature; substituting a sans-serif glyph or dropping
    the 3px ink border breaks the workshop voice.

    Default fill is butter; in a multi-card grid, cycle through sky / blush /
    mint variants. Each card carries its own ink pin via ::before.

    In a 3-card grid, set background-color per card via a .sky / .blush / .mint
    variant class and set the icon glyph per card (A/B/C or brand-relevant character).
