38 # Editorial Bleed — Design Specification
39
40 ## IV. Signature Design Elements
41
42 Editorial Bleed provides a structural vocabulary for 16:9 material where imagery
43 carries the argument and text is set on the image rather than beside it. The
44 neutral prototype paint exists only to expose hierarchy and slot geometry; it is
45 not an identity segment. Color, typography, logo, voice, and icon treatment
46 remain downstream decisions.
47
48 | Element | Template-specific behavior |
49 |---|---|
50 | No safe frame for pictures | Every `picture` slot reaches at least one canvas edge: full canvas on `hero_full`, `hero_side_scrim`, `chapter_full`, `quote_over_image`, and `closing_full`; an exact half on the two `split_bleed` variants; equal vertical bands on `triptych`; four `640×360` quadrants on `image_grid_four`. Text keeps an 80 px margin, pictures keep none. Insetting a picture inside a margin turns this system into an ordinary content layout. |
51 | Scrims are Slide-local, by PowerPoint's rule | PowerPoint paints Layout shapes beneath Slide content, and the picture is Slide content, so an overlay cannot be a Layout atom. Every scrim is therefore a Slide-local `data-pptx-role="decoration"` rect placed after its picture slot in document order. It travels as a prototype pattern, not as Layout-inherited chrome, and a page authored from this system must carry its own scrim. |
52 | Four overlay techniques | `hero_full` and `closing_full` use a bottom vertical fade (black `0 → 0.78 / 0.82`). `hero_side_scrim` uses a horizontal directional scrim (`0.88 → 0.30 → 0`) so the picture stays readable on the open side. `chapter_full` uses a full-canvas graded wash (`0.44 → 0.68`) that darkens toward its text. `quote_over_image` uses a raised-floor radial vignette (`0.42 → 0.72`) so a centered quote holds contrast while the frame edges fall away. |
53 | Overlays are gradients, never solid rects | A full-canvas solid `<rect>` is reserved for background ownership in a structured package and is compiled into the background plane, which sits below every picture. Every overlay here therefore carries a gradient paint even where the intent reads as a flat wash. Replacing one with a solid fill plus `fill-opacity` inverts its stacking and fails template validation. |
54 | Dark base plane | The single Master carries a dark background. The reusable structural fact is that the base plane is dark because text sits on imagery and reverses out of it; the prototype hex is replaceable preview paint, not an identity value. It is visible only where no picture covers it: the text half of the split pages, and all of `full_statement`. |
55 | A page without a picture | `full_statement` carries no picture slot. A system built entirely on imagery needs one page that stops, or every page competes for the same attention. |
56 | Captions instead of titles | `image_grid_four` declares no title slot, and `triptych` puts its title inside a top fade rather than above the images, because there is no margin band to hold one. Captions carry the reading order on those pages. |
57 | Text entry | Body and caption slots begin at the upper-left. Centered alignment is reserved for the quote page, whose composition is symmetric by intent. |
