Source brief: Visualization Concept — Fit - Part 4.0 (Athletic) - Concurrent Training.md Path: …/blog viz daily - temporary/concepts/Visualization Concept — Fit - Part 4.0 (Athletic) - Concurrent Training.md (modified 10:38 local today; confirmed against blog-viz-tracker.md, which logs this article as the 2026-06-03 run — “dual-trace interference scope + 5-control de-confliction console sub-archetype”).

Article: Fit pillar → Athletic track → Part 4.0 — Concurrent Training (the integration chapter).

Visual concept used

A portrait (1200×1500, 4:5) “Engineering Diagnostic Instrument” poster built directly from the brief’s native geometry — a timing / interference problem, not a split or a tug-of-war. Five stacked instrument zones, read top→down:

1. Master headline — TWO SIGNALS. ONE BODY. with the subhead framing the whole argument (strength = mTOR, endurance = AMPK, they fight only when they peak at once).
2. Interference scope — a dual-trace oscilloscope on a shared time axis, split into State A · SEPARATED (mTOR and AMPK pulses peak in turn, both complete, green ✓) and State B · OVERLAPPED (forced onto the same instant; the mTOR trace is clipped flat against a red ceiling with a dashed “ghost” of the lost signal and a ⚠ SIGNAL LOST flag). Carries the sprint-15-min-before-the-lift citation and the INTENSITY, NOT DURATION, FIRES AMPK HARDEST caption.
3. The asymmetry valve — a one-way AMPK ▶ suppresses ▶ mTOR arrow (live/red) with the reverse path greyed and blocked, encoding “cardio hurts strength more than strength hurts cardio → almost every rule protects the lift.”
4. Five-control de-confliction console — Phase Separation (slider), Intensity Cap (capped limiter), Modality Selector (full-width big lever, three-state ride/row ✓ · easy run mod · hard run ✕, Wilson 2012 cite), Fuel/Glycogen (gauge), and Block Bias (emphasised mode switch — the single most effective control).
5. Weekly scheduler + dual dashboard — three selectable 7-cell template rows (Lifter-priority / Engine-priority / Balanced) with the leg-day-vs-running warning chip, then twin Chassis ▲ / Engine ▲ dashboards, the three-line verdict logic, and the closing enhanced-lifter note.

Palette / type (Aether tokens): black ground (#000000), surface panels (#0B0B0D) with 27272A / 3F3F46 hairline borders, Inter for display/body and JetBrains Mono for technical labels. Two signal identities locked across the whole poster — mTOR = cyan 38BDF8 (build), AMPK = amber F59E0B (endure) — with red EF4444 reserved exclusively for the fault/collision state and the one-way valve, and green 22C55E for the “preferred / both-complete” cues. Clinical control-room mood; drama carried entirely by the separated-vs-overlapped contrast, not saturation. Avoided the tug-of-war and runner-vs-lifter clichés per the brief’s §7.

Outputs

• SVG: poster-2026-06-03-concurrent-training.svg
• PNG: poster-2026-06-03-concurrent-training.png (2400×3000, ~0.5 MB)
• Both also copied into the blog folder root: …/blog viz daily - temporary/

Renderer & verification

• Renderer used: CairoSVG (last-resort fallback). Playwright/Chromium was attempted first for font fidelity but the Chromium download exceeded the sandbox time limit; librsvg2-bin (rsvg-convert) was unavailable and could not be installed. CairoSVG produced a clean 2400×3000 raster.
• Verification: PNG confirmed non-empty (510,887 bytes > 50 KB) and dimensions exactly 2400×3000 via PIL. Poster also visually reviewed (Read on the PNG) — all five zones render correctly; the scope clip, one-way valve, five controls, scheduler rows, and dual dashboards are all legible.

Deviations / notes

• Fonts: CairoSVG has no Inter / JetBrains Mono installed in the sandbox, so it falls back to DejaVu/Liberation sans + mono. Visual hierarchy and the mono “instrument” feel are preserved; exact letterforms differ slightly from the Aether spec. (Re-rendering with Chromium + the real font files would tighten fidelity if desired.)
• SVG hygiene fix: initial render failed twice — first on -- sequences inside XML comments (illegal in strict XML), then on trailing NUL bytes left after an edit. Both were corrected; the final SVG is well-formed.
• One cosmetic adjustment: the scheduler section title was shortened from “WEEKLY SCHEDULER — SELECT A TEMPLATE” to “WEEKLY SCHEDULER” to stop it colliding with the Mon–Sun day-letter header.
• Downstream: the blog-viz-insert-daily task (10:30) can pick up poster-2026-06-03-concurrent-training.png for embedding.
