## Phase 70
Trim clip to selection applies source-frame endpoints within the current audible clip. Start rounds up and end rounds down to musical ticks; empty sub-tick ranges reject. Leading removal moves the timeline start by the same amount, preserving alignment. Source content, reference and clip gain/fade settings remain intact; project Undo restores the prior trim.

Apply sample-editor selection as audible clip trims with conservative frame-to-musical-tick rounding, preserved source content and one project undo step.
### Tasks and acceptance criteria
- [ ] Implement bounded C99 analysis/processing and accessible FLTK controls.
- [ ] Preserve source files, atomic error handling, history and callback safety.
- [ ] Pass meaningful core and GUI checks; document exact behavior and limits.

### Implementation status
Planned.
Implemented: native frame bounds trim audio inside its current audible region with conservative tick rounding and preserved timeline/source alignment. Core rounding/rejection/unchanged-state checks and GUI trim/project undo pass.
