Resume PDF on the Greg Kilmer letterhead

Each page of the PDF is laid over the brand letterhead with pdf-lib, both
kept as vectors. The letterhead carries the name, email, website and city, so
the resume's own header becomes the title, availability, profiles and date.
Type and two earlier-role lines are tightened so it stays on one page.
