* make top of "below-the-fold" be actually above the fold
* put all above-the-fold content except title and more details button
into that area
* kep below-the-fold area in fullscreen mode when title/credit gets untruncated
* increase title length to 180 (140 before reducing font size) - works nicely on
my 1600x900 laptop
* remove old styles which were intended to make the button smaller when the
panel is close but were mostly broken anyway and only caused the button to
twitch
To avoid redoing all the size calculation logic, we cheat and use a negative
margin to pull the below-the-fold content above the fold.
