A single E3 entry point cataloguing the design rationale: the 7 eidos RFCs
(color model/engine, typography/depth/shape/structure engines, scaling), the
3 arts subsystem design docs (connection/timer/session), and the cross-cutting
decision logs (LIBRO_VARIACIONES, GESTURES). Each entry gives status + the one
decision it records, linking the document for the full argument.
This delivers the "naming único" goal at the index level. The physical file
rename (*_RFC -> rfc-*, DESIGN_* -> design-*) is deferred: those names are cited
as provenance anchors in ~30 source files (eidos/lib/*.ts, arts/timer/*,
arts/color/*, tests), so a rename only pays off if every citation is swept in
the same pass. The index gives consistent naming without that churn.
