- TemplateSet: one strict handlebars registry per template set; strict
mode forced at construction, unparameterizable; enforcement test pins
missing-variable renders as Error::Render, never empty output
- EscapePolicy::{Html, NoOp}: explicit per-set escaper choice; Html
leaves the substrate default html_escape, NoOp registers
handlebars::no_escape; both postures pinned by golden render tests
- typed fallible registration of templates and partials; malformed
text is Error::Registration, never a panic; failed registration
leaves bookkeeping untouched
- set-level bookkeeping of template vs partial names (decision 1,
flagged for the gate): the substrate's register_partial is identical
to template registration, so the render-name rule cannot delegate to
it; TemplateSet::is_template exposes the tracking for the
w1-render-entry rejection
- per-set helper registration seam; zero custom helpers by default,
pinned by test (unknown helper is a typed render error)
- naming conveventions enforced by tests only, not at registration
(decision 2, flagged for the gate): consumer-facing engine API
stays naming-neutral per ADR-001/008
