Template: memory-wall

Look: introspective monologue, italic poem stacking on a back wall, right-aligned cascade for the climax. Sam Harris / Pico Iyer territory.

Visual identity (LOCKED — do not change):

• 4-slot typography arc: italic 600 → italic 500 hanging-indent → upright 700 pivot → uppercase 900 climax
• mix-blend-mode: screen over warm-bone color (#fff4dc)
• soft text-shadow + brightness boost
• Per-word fade with subtle Y-drift (soft tone) or pop+scale (present tone)

When to apply

✅ Good fit:

• Talking-head with a flat back wall (acoustic foam, plain plaster, soft bookshelf) on one side
• Single subject, fixed or near-fixed camera
• Voice-over feel: introspective, narrative, "I was thinking…"
• Mid-tone or dark backdrop (luminance < 180)

❌ Wrong fit:

• Bright window/sky backdrop → screen blend blows out
• Cluttered backdrop with text/graphics → conflicts with caption text
• Energetic / vlog / TikTok style → wrong vibe
• Multiple speakers / hard cuts → caption arc breaks

What agent decides per scene

Field	What	Example
plane.top/right/width/height	Where the wall plane sits in frame. Plane should HUG the side of the wall, not float over the subject.	{top: 90, right: 30, width: 720, height: 520} for 1280×720
plane.rotateY	Match the wall's perspective angle. Negative for right-side wall (text recedes left), positive for left-side wall.	-13 for a right-side wall at slight angle
plane.rotateX	Tiny vertical tilt if wall is angled up/down. Usually 0-2 deg.	1
font_scale	Multiplier on the locked cap-N base sizes. Tune for frame height.	1.0 for 1280×720, ~1.5 for 1920×1080, ~0.7 for 720p portrait
groups[].slot	Which of the 4 typography slots this group uses (1/2/3/4). Drives the arc.	See below
groups[].tone	"soft" or "present" — drives motion curve	"soft" for opening lines, "present" for pivot+climax

Slot assignment rules

Aim for ONE arc across the video: 1 → 2 → 3 → 4. Don't repeat slots if you can avoid it; don't skip slots without reason.

Slot	Use for
1	The opener. The "I was thinking" line. Italic, soft entry.
2	The dreamy continuation / modifier. Smaller italic, hanging-indent — feels like the second half of a sentence with some staggered drift.
3	The pivot. Upright (no italic), the syntactic turn. ("but suddenly", "and then…")
4	The climax. Big uppercase 900. The payoff line. Aim for ≤4 short words so the right-aligned cascade naturally wraps to 2-3 lines.

If the script is longer than 4 groups, repeat slot 1 or 2 for additional soft lines, but reserve slot 4 for the SINGLE climax.

Don't fight the template

If the user wants different typography, different blend, or different motion: use Standard mode (../../standard/). Don't try to override the locked CSS — the template's visual consistency is the whole point.
