add large2x and small2x image asset variables to helper
change small 2x to reference large image asset (since it is 2x res anyway)
margin/padding tweaks to page content/gallery, flexbox still wonky
add max-height to img to constrain flexbox
compile webfonts, subset page-title font, adjust copy padding/font sizes
replace bg image with css gradient
fallback bg color if gradient not supported
adjust copy font size
extract max-width to global img style instead of gallery specific
