Scale library type up 50%

Every font size in the library design multiplied by 1.5 — card title and
stamp, list title, meta, excerpt and tags, filter tabs, and the
prototype's header.

Geometry had to follow, or the larger type would have broken the layout
it sits in:

- The card grid drops from three columns to two. At 16.5pt in a 95pt
  column a card gets about nine characters per line and every title
  truncates; the text size is what sets the column count.
- Filter tabs grow 30pt -> 42pt tall, the card gains padding and a
  slightly squarer aspect, and the list's color chip, unread dot and tag
  chips scale with the text they sit beside.

Verified in both layouts against the live server. Suite passes.
