/*******************************************************************************
PROJECT PAGE — full-width layout on top of the Tufted theme

Loaded after tufted.css, theme.css and custom.css, which set type, colors,
code blocks, framed tables and dark mode. This sheet changes the page
geometry from the Tufte text rail to one centered column and adds the page's
components. Proportions follow the golden ratio: the column is phi/2 of the
viewport, splits are 1 : 1.618, and vertical rhythm steps by phi.

Contents: tokens · page frame · type · hero · buttons · demo embed ·
robot panels · method and stats · skill space · comparisons · showcase ·
ablations · media cards · bibtex · lightbox · responsive · motion
