Subject: [PATCH] feat(reports): leftover-map origin on leftover-map comparison
 graphic independently of leftover-map graphic leftover-map origin (v2.113.0)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Caption leftover-map comparison graphic leftover-map origin through leftoverMapComparePlotOriginBadge independently of leftover-map graphic leftover-map origin, leftover-map comparison leftover-pair leftover-map criterion leftover-map origin leftover-map item coordinates, leftover-map axis origin ticks, leftover-map axis share, and leftover-map singular values (ADR 0356). Distinct accessible name leftover map comparison graphic leftover-map origin {origin}. Rank-0 unused axes still name leftover-map origin (0.00, 0.00). leftoverMapPlotOriginBadge stays leftover-map graphic leftover-map origin keys. leftoverMapComparePlotTickAxisBadge stays leftover-map comparison graphic leftover-map axis origin tick keys. Do not invent leftover-map origin from leftover-map item coordinates ζ. Do not mix #877. Do not mix #890 stale ADR 0347 / v2.104.0 identity.

+
+## Context
+
+ADR 0355 already names leftover-map graphic leftover-map origin
+`leftover-map origin {origin}` when leftoverMapPlotOriginBadge returns a usable leftover-map origin caption.
+Rank-0 unused axes still persist leftover-map origin `(0.00, 0.00)`
+(`formatLeftoverMapCoordinatePair(0, 0)`). Leftover-map comparison graphic leftover-map origin stayed unnamed
+that increment (`leftoverMapPlotOriginText` returned null for comparison).
+Do not invent leftover-map origin from leftover-map comparison leftover-pair leftover-map
+criterion leftover-map origin leftover-map item coordinates `ζ`. leftoverMapPlotOriginBadge stays leftover-map graphic leftover-map origin keys from ADR 0355.
+leftoverMapCompareListCriterionBadge stays leftover-map comparison leftover-pair leftover-map
+criterion leftover-map origin leftover-map item coordinate keys from ADR 0354.
+leftoverMapListCriterionBadge stays leftover-map pair leftover-map criterion leftover-map origin leftover-map item coordinate keys from ADR 0352.
+leftoverMapComparePlotCriterionBadge stays leftover-map comparison graphic leftover-map criterion leftover-map origin leftover-map item coordinate keys from ADR 0350.
+leftoverMapPlotCriterionBadge stays leftover-map graphic leftover-map criterion leftover-map origin leftover-map item coordinate keys from ADR 0347.
+leftoverMapPlotTickAxisBadge stays leftover-map graphic leftover-map axis origin tick keys from ADR 0343.
+leftoverMapComparePlotTickAxisBadge stays leftover-map comparison graphic leftover-map axis origin tick keys from ADR 0344.
+leftoverMapCompareAxisTickBadge stays leftover-map comparison leftover-axis origin tick keys from ADR 0345.
+leftoverMapAxisTickBadge stays leftover-map leftover-axis origin tick keys from ADR 0346.
+
+This increment names leftover-map comparison graphic leftover-map origin as leftoverMapComparePlotOriginBadge.
+Leftover-map comparison graphic leftover-map origin stays
+`leftover map comparison graphic leftover-map origin {origin}`
+when leftoverMapComparePlotOriginBadge returns a usable leftover-map origin caption, so it stays distinct from leftover-map
+graphic leftover-map origin
+`leftover-map origin {origin}`,
+leftover-map graphic leftover-map axis origin ticks
+`leftover-map axis {axis} origin tick {value}`,
+leftover-map comparison graphic leftover-map axis origin ticks
+`leftover map comparison graphic leftover-map axis {axis} origin tick {value}`,
+leftover-map comparison leftover-axis origin ticks
+`leftover map comparison leftover axis {axis} origin tick {value}`,
+leftover-map leftover-axis origin ticks
+`leftover axis {axis} origin tick {value}`,
+leftover-map comparison leftover-pair leftover-map criterion leftover-map origin leftover-map item coordinates

+this increment. It does not add columns. Do not invent a leftover score. Do not invent a theta.
+
+This protected increment uses **0356** / **v2.113.0** so it does not collide with leftover-map graphic leftover-map origin independently of leftover-map comparison leftover-pair leftover-map criterion leftover-map origin leftover-map item coordinates

+## Decision
+
+On leftover-map comparison graphic, caption leftover-map origin
+when leftoverMapComparePlotOriginBadge returns a usable leftover-map origin caption. Rank-0 unused axes still name leftover-map
