/*=== Base =====================================================================
The bones every game is built on: the page, the screens, the cards, the keys with a hard offset shadow that press
flat under a tap, the lobby (the code, the seats, the roles) and the home screen's hero. Written on semantic tokens
a game's own stylesheet sets from its palette, after this one: what is a background, a plate, a key, a border, the
text, the accent. The defaults below are SymbolSync's, the series' type: its palette's colors by the names its
palette.css gives them (ink, steel, sage, paper, tan), so a page whose palette is named as SymbolSync's needs no
mapping of its own, as the template's. Every game maps its own palette onto these, and one that wants rounded corners,
a softer press or a different entrance sets --radius, --snap and --screen-in, and one with a second face for its
title, keys and headings sets --display-font (and --display-weight, for a face with no bold); anything it wants otherwise it overrides
by the same selector in its own stylesheet, which loads after this one. Mobile first: a phone in portrait is the
layout everything else grows from */
