Product detail: resources section layout 3 "Hardware option"

- The Resources Section Layout select gained a third value, hardware
  ("Layout 3 - Hardware option"): Technical Highlights spread over two
  columns, no resource cards
- ProductShowJsonRenderer::resourcesBand() emits the same envelope with
  items: [] for hardware even when cards are maintained, so the cards
  stay on the product and reappear when switching back to layout 1 or 2
- Spec v1.27 (resources.sectionLayout values)

 | 1.24 | 2026‑10‑23 | **Interface change (additive).** New frontend layout **22 Solution Group Page** for the eight solution group hero pages (zones hero = `colPos1`, main = `colPos0`). Element order: `vitec_markethero` + `vitec_introparagraph` in the hero zone; `vitec_marketintro` 2, `vitec_introparagraph` + 4 `text_only` cards (challenges), `vitec_introparagraph` + 4 alternating `horizontal`/`horizontal_reverse` cards (capabilities, bullets as `<ul>`), `vitec_usecaselist` (testimonials, shipped hidden until stories are picked), `vitec_marketinsights`, `vitec_ctabanner` in main — imported from the agency Template‑06 workbooks by `vitec:import-solution-group-workbooks`; page properties as on the sub‑solution pages. |
 | 1.25 | 2026‑10‑23 | **Interface change (additive).** The markets branch is aligned with the agreed agency structure: `/markets`  eleven market hero pages  their sub‑market pages (the use‑case level stays sections per 7.17). New frontend layout **23 Market Hero Page** (zones hero = `colPos1`, main = `colPos0`): `vitec_markethero` (CTA anchors `#submarkets`) + `vitec_introparagraph` (header carries the hero H1) in the hero zone; `vitec_marketintro`, `vitec_introparagraph`, sub‑market `vitec_card`s whose `primary_cta` links the child page, `vitec_ctabanner` in main (`vitec_customerlogos` and `vitec_usecaselist` ship hidden until filled editorially). Imported by `vitec:import-market-hero-workbooks`; the tree itself by `vitec:align-market-pages` (renames with slug redirects, child slugs normalised — this also repairs embedded‑slash slugs). Sub‑market pages gained the full page‑properties set. |
 | 1.26 | 2026‑10‑26 | **Interface change (additive).** Product detail resources band simplified (customer CR): the `resources` envelope gains **`sectionLayout`** — `50-50` (default) \| `33-33-33` — from the new per‑product select *Resources Section Layout* (Layout 1: Technical Highlights left, resource cards right, 50/50; Layout 2: highlights over two columns, cards in the third). Capabilities leave the band editorially; the TCA fields `capabilities`, `datasheets` and `downloads` are parked in the Misc tab — all three stay in the payload unchanged. The automatic newest‑datasheet/documentation cards remain deferred; meanwhile the manual card `restype` vocabulary gains `datasheet` and `brochure` — a pinned datasheet card links the download record and stays current because the download route always serves the newest file. |
+| 1.27 | 2026‑11‑02 | **Interface change (additive).** Product *Resources Section Layout* gained the value `hardware` (“Layout 3 - Hardware option”): `resources.sectionLayout = "hardware"` — Technical Highlights over two columns, no resource cards (`resources.items` is emitted empty even when cards are maintained, so they reappear on a switch back). |
