The masthead's separator between "quantus mining" and "this is sparta" is now the caution mark rather than a middle dot, scaled to the line it sits on. `.mark-tagline` gains an explicit `line-height` for that reason: the image is sized from it, and a line height inherited from `body` would quietly resize the mark the day the body's changed. The height is declared twice — `1.4em` then `1lh` — which is the same number here precisely because the line height above is stated, so a browser that does not know the unit lands in the same place rather than near it. `alt` is empty and `aria-hidden` is set, on purpose. The mark stands in for punctuation and the words either side already say what it says; announcing it would be reading the separator aloud. Imported as a hashed asset like the portrait, and it keeps its own transparency rather than being given a ground — the masthead sits on a radial glow, not a flat surface, so a background would show as a rectangle.
