Tone down hero name, crop new avatar, drop em-dashes

Make the name a quiet heading and let the one-line thesis lead the hero.
Replace the portrait with a center-cropped 4:5 version of the new photo
(downscaled 1.2 MB -> 91 KB) and drop the now-pointless grayscale hover.
Remove em-dashes from copy (restructured prose; en-dashes for year ranges;
mid-dot in the page titles).
