feat(shop): 37 target = in-class raw template literals (developer form)

- separate view.html files dropped; every render() now carries its
  '-- 37 target:' literal above the hand-lowered body — the pair is
  the DX referendum in one file
- story 37 re-pointed: raw multi-line literal + {{ }} auto-escaped
  typed holes + {!! !!} raw slots; structural control stays if/for;
  w:if/w:for and .html files demoted to later; forks revised
- rebuild verified on untouched toolchain

-- **Templates compile or they don't exist (story 37).** The `.html`
-  files here are the TARGET: when 37 lands, `woc` compiles each against

-  `render()` methods in `view.wo` disappear. Until then the `.wo` files

 Forks the spec must settle (REVISED 2026-08-23 for the compiled-template
 direction):
 
-1. **Template pairing** — Vue-SFC style (one `view.html` whose
-   frontmatter/`<script>` block declares the fields) vs paired files
-   (`view.html` + a `.wo` view class it compiles against). Leaning:
-   paired — the class stays ordinary `.wo`, the template is pure markup.
-2. **Directive surface** — the minimal set: `{{ expr }}` (auto-escaped),
-   a raw spelling for prebuilt fragments (slots), `w:if`, `w:for`,
-   `w:class`-style conditional classes. Anything beyond is YAGNI until a
-   sample demands it.
+1. **The raw-literal spelling** — backticks, triple quotes, or another
+   delimiter; and the raw-slot spelling inside it (`{!! !!}` vs `${}`
+   staying unescaped). One rule: `{{ }}` always escapes.
+2. **Directive surface** — v1 ships NONE (structural control is `if`/
+   `for` composing literals); `w:if`/`w:for` and separate `.html` files

 3. **Escaping default** — `{{ }}` escapes ALWAYS (safer than today's

    is greppable.
