/*
 * CP-21 Message — app/components/ui/message_component.rb
 *
 * Chat bubble: own side right-aligned on the accent tint, the other side
 * left-aligned on the surrounding surface's field fill. Ink text on both fills keeps AA at
 * body size (white on --color-accent does not). Bubbles cap at 85% of the
 * thread width so a long message never reads as a full-width block, and
 * long URLs break rather than overflow the 375px referrer column.
 *
 * Token vars only — enforced by test/lint/css_token_lint_test.rb.
