The tooltip was clamped to a fixed 90px margin while it can grow to 260px,
so bars near the left edge pushed it outside the panel and cut the title and
view count. It now clamps against its measured width and rests against the
chart edge instead of staying centred.
Bars are HTML now instead of SVG: the SVG <title> tooltip barely showed up in
Firefox and thin bars were hard to hit. Each bar sits in a full-height hover
target, hovering shows the video's title, views and age, clicking opens it. A
legend explains the median line and the highlighted bar, and baselines now
cache titles for those tooltips.
Scores every card against the median views of its own channel's last N
videos, badging the thumbnail above the duration stamp. Shorts and regular
videos are scored in separate pools, live streams in none. Baselines come
from YouTube's InnerTube endpoint, one request per channel, cached a day.
Interface in English and Turkish.
