fix(panel): keep the party-board hint clear of the dock

The hint line is a <p> whose user-agent 1em top margin was never reset,
so at 1920x1080 its box rendered at ~954-988px, under the dock (top edge
950px). Reset the margin, restore the PANEL-SPEC §2 27px/600 size, and
move the hint up to top: 896px so its 37.8px line box ends at ~934px,
16px above the dock. The dock keeps its 84px height and 46px inset.

Add a source-level regression test asserting the hint's margin reset
and that top + font-size x line-height sits at least 12px above
1080 - dock bottom - dock height.
