Five PerTabSurface tests pin the input contract so future refactors
can't silently regress it:
- typed_text_enters_pending_input_after_clicked_viewport: typing
reaches the sidecar once a click establishes keyboard focus.
- scroll_delta_enters_pending_input_after_wheel: scroll deltas
combine across multiple wheel events.
- viewport_size_changes_after_stable_second_measurement: viewport
resize is debounced behind a "same size twice" guard.
- scroll_after_click_keeps_keyboard_focus_and_typed_text: the bug
fixed last commit cycle — scroll drops the buffered click point
but must keep keyboard_focus and buffered keystrokes.
- typing_without_a_prior_click_is_rejected: typing without focus
returns false, so a future refactor can't accept stray keystrokes.
No instrumentation eprintln/log added in production paths
(per CLAUDE.md NO LOGGING). cargo test ely_app --bin ely_app: 102
passed.
