        | независимо от исходного цвета, а invert(0.2) поднимает его до
        | #333 — спокойного тёмно-серого.
        |
        | Раньше тон задавался прозрачностью 0.78. Так нельзя: у ВКонтакте
        | и Telegram значок — сплошная плитка, а у MAX тонкий контур, и одна
        | и та же прозрачность гасила его заметно сильнее соседей.
        |
        | Насыщенный чёрный оставлен НАВЕДЕНИЮ: пока на значок не навели,
        | он не должен выглядеть нажатым.
