Redesign the stats pages after first review
The per-commit page now carries the section hero, uses the commit
subject as its serif title (no more monospace hash crammed into a
display heading), and shows the date and full hash in a legible light
meta line built for the dark band rather than the pale coverage-line
styles borrowed from elsewhere. The change-log rows are whole-row
links with a warm hover wash across the full width, the log heading
stacks its "newest first" note under the title instead of floating it
beside the display type, and the footer's Site stats link sits tight
under the wordmark at full contrast with a gold underline accent
instead of greyed-out and adrift.
