Page-in animations drop 'forwards' fill mode — a .page-transition base class
(opacity:0) serves as the initial state, and .page-transition--in-{left,right}
force opacity:1 after the animation ends, preventing a flash-back-to-invisible
on some WebKit versions. Sidebar expands at 1440px instead of 1280px.
Glass desktop toolbar loses the rounded card border in favour of a flat
accent-top-border + bottom border consistent with other module headers.
