Blog Viz Poster — 2026-06-02

Date: 2026-06-02 Source brief: Visualization Concept — Healthy - Sleep Part 1.0 - The Architecture of Sleep.md (path: …/blog viz daily - temporary/concepts/) — the most recently modified concept (10:37), confirmed as today’s freshest brief. Article: Healthy pillar · Sleep track · Part 1.0 — The Architecture of Sleep (Part 1 of 5)

Visual concept used

A hypnogram drawn as the cross-section of a building at night — the brief’s non-negotiable hero object, rendered literally. The horizontal axis is TIME (LIGHTS OUT → WAKE, ~8 h with hour ticks); the vertical axis is DEPTH (AWAKE · REM · N1 · N2 · N3 DEEP on a left ruler). The sawtooth trace plunges into big N3 troughs in the first two cycles and shallows toward morning while the REM bands lengthen, so the night’s asymmetry is obvious at a glance: warm amber deep wedges crowd the left (THE BODY · physical repair) and cool violet REM ribbons stretch across the right (THE BRAIN · cognitive repair). A left-to-right amber→violet under-curve gradient encodes the body→brain gradient before a word is read. The emotional payload sits as two red guillotine cuts — a solid right-hand cut with a hatched amputation zone (WAKE EARLY → LOSE REM) and a dashed left cut (LATE TO BED → COMPRESS DEEP) — beside the headline math A 6-HOUR NIGHT ≠ 75% OF 8. A two-room cutaway floorplan (THE BODY / THE BRAIN with their stage-specific jobs) is bolted under the curve, and the thesis lockup YOU DON'T TAKE SLEEP. YOU BUILD IT. closes the bottom. Style = the brief’s proposed “Clinical Nocturne” — a sibling to the Fit pillar’s Engineering Diagnostic Instrument style, same instrument-grade labeling and single-alarm-color (red) discipline, rendered after dark. Banned clichés (sleeping figure, moon, alarm clock, symmetric pie/stacked bars) all avoided.

Palette (from §5 of the brief): background ink #0B0F1A; body/deep amber #E8A23D; brain/REM violet #8B7CF0; text off-white #E6E8EE / slate #A1A1AA; the one alarm color, signal red #FF5C5C, reserved exclusively for the two cuts and the 6 ≠ 75% math.

Outputs

• SVG: outputs/poster-2026-06-02-architecture-of-a-night.svg (also copied to …/blog viz daily - temporary/posters/)
• PNG: outputs/poster-2026-06-02-architecture-of-a-night.png — 2400×3000, ~288 KB (also copied to the posters/ folder for the downstream insert task)

Renderer & verification

• Renderer used: CairoSVG (2× = 2400×3000). Playwright/Chromium and rsvg-convert were both unavailable in the sandbox (no apt/chromium); CairoSVG was installed via pip and used as the fallback.
• Verified: PNG is 2400×3000 as expected and ~288 KB (> 50 KB threshold); SVG parses as well-formed XML; layout/text visually inspected via a downscaled preview and corrected (label overflow, math box width, thesis sizing).
• Font note: CairoSVG has no Inter/JetBrains Mono and falls back to DejaVu Sans (wider metrics). Type sizes were tuned so all labels fit; on a Playwright/Inter render the layout would have slightly more breathing room.

Deviations / notes

• Headline: used A NIGHT HAS A SHAPE. (the brief’s “cleanest, most poster-like” option) with the provocation surfaced separately as the red math callout.
• Two posters exist for today. An earlier run (01:43) already produced poster-2026-06-02-vo2-max-and-mitochondria for Fit/Athletic Part 2.1 (the tracker’s prior “next up”) and its record blog-viz-poster-2026-06-02.md. This run targets the newer Sleep Part 1.0 brief (modified 10:37), so this record is filenamed with a slug suffix to avoid overwriting the earlier VO2 record.
• Path-reconciliation policy (from prior runs) still applies: the live workflow folder is …/blog viz daily - temporary/; the scheduled-task file’s hard-coded local_dbaa9cdd outputs path is not mounted in run sessions, so outputs are saved to the session outputs folder and copied into the connected posters/ folder.
