/**
 * Provenance Highlighting Styles
 *
 * ARCHITECTURE: CSS styling for inline diff highlighting
 * WHY: Visual distinction between content sources in progress notes
 * TRADEOFF: Subtle highlighting vs bold colors - chose subtle for clinical readability
 *
 * Color scheme (matches ProvenanceSource enum):
 * - carried_forward: Green - unchanged from yesterday
 * - today_evidence: Blue - from user's clinical input
 * - llm_synthesis: Amber - AI generated/inferred
 * - lost_content: Red - was in yesterday's note, missing today (detail loss)
