[Alexander-Mitrofanov]

Addresses the GUI revision request on #299. This follow-up depends on #299 and targets its branch, feat/297-gui-sessions.

The input panels now follow Sequences → Seed → Output → Model & Energy → Query → Target → CLI-only. Controls use the requested row order and aligned inputs; SHAPE sits beside each strand's accessibility inputs, shared accessibility flags stay synchronized, and helix controls sit under Model & Energy. The three-way seed selector and accessibility modes disable irrelevant fields and omit their stale values from computations and saved parameters.

• Use “IntaRNA package”, put Compute/Evaluate first, and follow it with Input Parameters, Examples, Store, Load and Reset. Give sequence/CLI information the available width.
• Accept up to 50 FASTA records per field and 5,000 nt per record, enforcing longest selected query × longest selected target ≤ 1,000,000. Raise FASTA upload/JSON limits to accommodate these batches, warn about ignored header descriptions, place start indices before record counts, and allow scrolling in both directions.
• Group compact CSV column names with description tooltips and per-group Select/Deselect actions. Prediction defaults to 10 interactions plus ED1/2 and seed energy/start columns; evaluation selects all energy columns. Preserve these defaults explicitly in native-compatible JSON, while existing imported files retain native defaults for omitted settings.
• Rename Sessions to Results, order Show/Hide before name, ZIP and deletion, and restore inputs from header/name selection. Compact numeric table headings/padding and distinguish table headers from selected rows. Folded export and deletion continue to preserve edited inputs.
• Update examples, usage documentation, ChangeLog and regression coverage.

Validation:

• npm test --prefix gui: 20 passed.
• Real-WASM scripts/wasm/test-browser.py in Chromium and Firefox at a nested URL: passed. Includes mode availability, stale disabled values, explicit-seed JSON restoration, synchronized controls, grouped CSV actions, header selection, existing session/ZIP behavior and cancellation. Desktop/mobile screenshots inspected; all panels fit at 390 px without document overflow.
• node scripts/wasm/smoke-protocol.mjs <staged-engine>: native-reference checks and byte-identical JSON archive replay passed.
• Fresh GCC 14 release make tests -j2: all nine API/CLI groups passed. Existing CLI fixtures were linked into the out-of-tree build's tests/data directory.
• Static staging/digest checks, JS/Python/shell syntax and git diff --check: passed.

The C++ engine and worker protocol are unchanged. Browser checks reuse the parent's compiled Emscripten 4.0.23 / ViennaRNA 2.7.2 assets with their original provenance. Sessions remain page-local; the new sequence cap applies to the largest selected pair rather than total batch work.
