+ * The operator takes (or picks) an image, `acquire(blob)` sends it to the Flask
+ * proxy, and the result - quote table, outcome, failures, overlay - is shown on
+ * the image. `acquire(blob)` is the single entry point on purpose: the agent
+ * camera (#3) will call it with its own blob and reuse everything below.
+ *
+ * Config comes from window.__visionCfg (set by the template):
+ *   executeUrl, imageUrlTpl (with a 0 placeholder for the result id), taskId,
+ *   taskType, subtasks, labels.
+ * Run context (lot, serial, production run) is read lazily through `ctx()`,
+ * which the template binds to the parent task component.
