/* DirtyMinds — Conversations module stylesheet
 *
 * Phase 1 (conversations-build-plan §Phase 1). The visual layer for the
 * standalone component js/conversations-ui.js. Visual SoT is the mockup
 * _Other/mockups/conversations-mockup.html — these classes are the BEM-lite
 * `conversation-*` re-expression of that mockup (CLAUDE.md CSS rules).
 *
 * Token discipline: every colour/space references a base.css token by name,
 * but always with a STANDALONE FALLBACK — `var(--color-bg, #0d0d0f)`. base.css
 * defines the exact tokens the mockup uses, so this sheet is correct inside the
 * app AND self-sufficient in the dev harness (which has no base.css). The two
 * marker colours the module owns (branch 🧵 / spin-off →) are not platform
 * tokens, so they're declared module-scoped on `.conversation` below.
 *
 * No release bump: this file is loaded only by the dev harness in Phase 1
 * (outside dist/, worker dark); it gets wired into the app in Phase 5.
 *
 * Dependencies: none (optionally layered over css/base.css in the app).
