/*
 * G13 research annex + evidence drawer (Plans 03/04).
 * Self-contained: annex cards/navigation, item-kind chips (semantic palette
 * from the graph editor, §6, re-derived for light surfaces with dark text so
 * color never carries meaning alone — every chip also carries its label),
 * permanent evidence/finding pages, and the drawer/bottom sheet.
