* `custom` -- Instrument the applet with user-provided code snippets. The user has to do the measurements on their own.
* `memory` -- Measure memory usage.
* `time` (default) -- Measure elapsed time.
* `time` (default) -- Measure elapsed time via exception-based instrumentation using a card reader.
* `stats` -- Collect API usage statistics.
* `spa-time` -- Measure elapsed time via power trace analysis using an oscilloscope.

NOTE: The `spa-time` mode uses Simple Power Analysis (SPA) to measure execution
time by capturing the card's power consumption for the target method as a power trace via
oscilloscope connected through a LEIA smartcard board. Timing is extracted by
locating a user-provided delimiter pattern inside each captured trace.
This mode is currently under development and available in the
link:https://github.com/crocs-muni/JCProfilerNext/tree/spa-time[`spa-time` branch].
