Detailed Description

Forward mode's independent check runs where rocketcea is not installed.

The API image leaves rocketcea out on purpose (it builds CEA from Fortran; requirements-base.txt),
and handcheck imported it first thing: POST /api/evaluate on the LE4 (3) stand came back with
``handcheck = {"rows": [], "error": "ModuleNotFoundError: No module named 'rocketcea'"}`` and the
page said only "Independent check: unavailable". Nothing tested handcheck at all.

Without rocketcea the textbook rows (mass balance, F = Cf Pc_ns At, Isp, the injector's Sutton 8-1,
Rupe M, stay time) need no CEA and must run; c* is checked against the committed wide CEA table;
the rows that need live CEA say so, and ``note`` says why.

The wide table spans O/F 0.1-20 where the design's cache stops at 2.5: past the edge the
model's c* is the edge's, the table's is the point's, and the row says so.
