V-notch default-action carry-forward: close #11790 + port AreaSeries.curve prop as fresh PR unless Richie pivots by 2026-06-18 EOD UTC

Original commitment (2026-06-17 12:58Z thread reply, ts 1781701116.260979): rebase #11790 onto main by EOD UTC unless Richie pivots. Started rebase 2026-06-17 ~20:00Z, hit immediate conflict against Stefan's ALL-1777 chart-primitives merge (commit 1/24 SiteEnergyCharts.tsx). 25-commit conflict resolution on chart files for a fix that hasn't been visually verified is the wrong shape — surfaced to Richie 2026-06-17 20:15Z (thread ts 1781727303.310799) with three options (a) squash-then-rebase, (b) close+port curve prop as fresh small PR, (c) defer until preview scrub. Committed default: (b) close-and-port unless he pivots by 2026-06-18 EOD UTC (~23:59Z). At trigger: (1) check V-notch thread for any Richie reply since 2026-06-17 20:15Z; if reply present, follow his direction; (2) if no reply, execute path (b): close PR #11790 (no --delete-branch), update Linear BOLT-1193 to 'parked - V-notch curveMonotoneX attempt + brush-zoom/auto-densify both archived; reopen branch if needed', cut fresh branch winston/bolt-1193-areaseries-curve-prop off latest origin/main, cherry-pick just the AreaSeries.curve prop change (commit c201fb0799 has the relevant edges piece), open mini-PR with the V-notch context in the PR body, post one-line confirming reply in the thread.
