feat(site): show discreet # permalinks on landing section titles

The landing sections had ids but no visible anchor, unlike About/Legal.
Add a hover-revealed # link on each section title (Status, Features,
Screenshots, Values, FAQ, Collaborate, Get it) and widen the reveal rule
beyond .doc so it applies to the home too.
