Illustration 2.1 — Four outcomes of the Tier-0 gates¶
Referenced in Chapter 2. Four equally-weighted cards: abolish, judge, redirect, proceed. Monochrome only — strokes and text in the theme's fg colour, fills in the theme's bg colour. No hue does any work. Equal weight across all four cards is deliberate: the book produces all four outcomes, not just the last.
Encoding without colour¶
- Equal cards — same width, same border weight, same typography across all four. No card is visually privileged. This matches the book's claim that a method producing only proceed is not a method.
- Small-caps labels — Abolish, Judge, Redirect, Proceed rendered in the same letter-spacing and weight. Hierarchy is refused on purpose.
- Horizontal rule under each label — a quiet half-opacity line that separates the name from the description without introducing colour or shading.
- Band strap — top micro-label ("Outcomes after the Tier-0 gates") and bottom caption strip together frame the four cards without bracketing them in a heavier frame.
Dark-mode test¶
Toggle the theme (top right). Borders, strokes, rules, labels, captions — all flip to white on black via var(--md-default-fg-color) and var(--md-default-bg-color). No per-theme SVG, no asset duplication, no second export.
Where SVG + monochrome shines¶
- Printable as-is. Zero render cost to PDF or paper.
- Accessible:
<text>nodes searchable by Lunr;<title>gives screen-reader label. - Reviewable in git: a line edit is a visual change, diffable.
Where it pushes back¶
- Equal-weight cards give the reader no "look here first" cue. That is the whole point of the illustration — but if a reader skims the page, they may not feel the force of "all four are available". The chapter text around this illustration has to carry that weight.
