/* Widget 59: a study's trend chart, inside its study box (content-intelligence/study_chart.py,
   assets/js/study-chart.js; owner, 2026-10-05). The page carries the finished chart; the script
   draws it in and adds the scrubbing. Lines are SVG stretched to the plot (strokes kept thin with
   non-scaling-stroke); every label is HTML, so text stays readable at any width. Colours are the
   site's tokens, so the chart follows data-theme dark mode with the rest of the page. */
