| 50 | # Presentation Core 4:3 — Design Specification |
| 51 | |
| 52 | ## IV. Signature Design Elements |
| 53 | |
| 54 | Presentation Core 4:3 provides a structural vocabulary for rooms and devices |
| 55 | that still project in 4:3: classrooms, lecture halls, academic sessions, and |
| 56 | meeting rooms with fixed legacy displays. The neutral prototype paint exists |
| 57 | only to expose hierarchy and slot geometry; it is not an identity segment. |
| 58 | Color, typography, logo, voice, and icon treatment remain downstream decisions. |
| 59 | |
| 60 | | Element | Template-specific behavior | |
| 61 | |---|---| |
| 62 | | Shared frame | One restrained Master background and a 56 px horizontal safe frame keep the roster coherent. The title band occupies `56 36 912 64` on every titled page, and the content field runs from y 136 to y 712. | |
| 63 | | Narrower column budget | The 912 px content width gives each half-page column 440 px and each third 288 px. Body copy in split layouts steps down one size relative to single-column pages so line length stays readable instead of forcing hyphenation. | |
| 64 | | Vertical preference | The taller field makes stacking a first-class option rather than a fallback. `stacked_split` divides the page into two full-width bands; use it where a wide canvas would reach for a left/right split. | |
| 65 | | Square-leaning metric grid | `kpi_grid` places four metrics in a 2×2 block over one evidence panel instead of a single four-across row, which would compress each metric below a readable width on this canvas. | |
| 66 | | Image system | `picture_caption` uses a typed `picture` slot occupying the full left field with an independent caption rail, matching the near-square crop that 4:3 rooms display well. | |
| 67 | | Data system | `chart_insight` and `table_summary` declare typed `chart` / `table` slots. Their authored groups remain complete SVG fallbacks; optional replacement metadata can materialize PowerPoint-native data objects only when that export path is requested. | |
| 68 | | Text entry | General body and object slots begin at the upper-left. Centered alignment is reserved for KPI values, short process nodes, the timeline takeaway, and focused statements. | |
| 69 | | Neutral framing | Pale panels and hairlines reveal intended zones in the prototype; downstream deck or brand skin controls final paint. | |
| 70 | |
