Supercard · v3.10 Atlas
Supercard
A screenshot-shareable, single-emphasis-per-block knowledge card: a cognitive prosthesis. Every region stands on its own: a stranger seeing only a cropped screenshot still gets one complete idea. Strict grayscale, SF Pro Rounded, no chrome.
The spec
One URL. The whole spec.
Everything an agent needs to build, render, or judge a Supercard (principles, grammar, blocks, pipeline, tokens) lives in one self-contained
llms.txt file. Point any LLM at it; there's nothing else to fetch.

Documents
The Payba Invoice
First Superdoc: the Supercard soul on a US Letter sheet. A sample invoice for a creator membership product — strict grayscale, hairlines, three type sizes with weight and ink doing the hierarchy, tabular figures, one page, with a tagged-PDF twin to download. Engine: ADR-0021.
Cards
Outside Eyes
First card declaring frozen_at_version 3.10.0. Exercises the interface-skills cut: R-36 subheads as real headings, R-37 glyphs at the contrast floor, R-38 charts named by their data, R-39 role tokens, R-40 the card as a document, R-41 balanced display wrapping and R-42 smart punctuation. Strict grayscale, hairline surface, 64pt beats.
Rendered as Written
First card declaring frozen_at_version 3.9.0. Exercises the robustness cut: the R-33 faithful-markdown treatments (real quotes with attribution, checkmark checklists, numbered process flows), the R-34 measured fit and rhythm, and the R-35 column and area charts drawn from the shared geometry module. Strict grayscale, hairline surface, 64pt beats.
Data, Aligned
First card declaring frozen_at_version 3.7.0. Exercises the V3.7 cut: the R-27 cover eyebrow above the title, the R-30 grayscale bar and line charts, the R-31 stat-grid and stat-callout numeric anchors, and the R-28/R-29 alignment fixes (no doubled header rule, fixed-grid columns). Strict grayscale, hairline surface, 64pt beats.

The Reading Layer, Refined
First card declaring frozen_at_version 3.5.0. Exercises the reading-layer cut: R-19 body metrics (17/26, −0.01em, word-spacing normal), the R-20 three-step text-ink ladder (every step clears WCAG 4.5:1), the R-21 three-size reading core, and the R-15 64pt default beat gap. Hairline surface, strict grayscale.
Plain Language as Substance
First card declaring frozen_at_version 3.4.0. Exercises the V3.4 cut end to end: Tile head step, 64pt beat gaps (R-15), surface-tinted stat callout (R-16), eyebrow + tagline pairs (G-14), mobile paragraph cap (G-12), readability target (G-13).
Gestalt Principles
Your visual system groups, splits, and completes a scene into objects before you're aware of looking. The Gestalt principles are the catalogue of rules it uses.
Spaced Repetition
Reviewing at widening intervals beats cramming: roughly double the long-term retention for the same total study time.
