A lap can span many minutes, so plotting one flat value per lap hid real within-lap variation -- a single-lap hill repeat rendered as a dead-flat line despite the pace/HR swinging throughout it. The actual pace/HR trace now comes from activity_samples (per-second telemetry) when available, looking up each sample's enclosing lap only for the target band/phase color. Falls back to the previous lap-stepped rendering when an activity has no samples.
