Coordinator lesson from the art-deco lane: `field.text` attribute access on a
bare-string seed/settings value errors the whole block to empty (dead band).
eyebrow/headline/subheadline/description now use `|get:"text"|default:` so the
hero accepts {text,...} objects OR bare strings — same fix art-deco shipped in
f2c8b36. cta/logoText object fields are builtin-typed and stay direct.
Also audited per coordinator: no ::icon:: shortcodes in any template/block
(only CSS ::-webkit pseudo-elements); master_pages.json untouched this lane.
