/* 03-agent-chat - part of the former static/style.css.
 *
 * The stylesheet is split by area, but the split is mechanical: rules were
 * moved verbatim and NOT regrouped. The numeric prefix is the load order, and
 * that order is what preserves the cascade. A rule sits in the file its
 * original position fell into, so an area's rules are not all in its file and
 * a file is not only that area's rules.
 *
 * Do not reorder the <link> tags in static/index.html, and do not move a rule
 * between files: with 1,151 redeclarations and 1,886 !important in this
 * cascade, either can change which declaration wins.
 *
 * static/index.html and the PRECACHE list in static/sw.js must agree on this
 * order. tests/test_static_stylesheet_manifest.py and
 * tests/test_css_computed_style_snapshot.py fail if that drifts.
