plan(narrative): design the interface, not just its routes

[frapercan]

The previous revision specified information architecture and called it a book. It was not. The front door is still a SaaS hero (gradient orbs, blur-3xl, a pulsing dot), which says product, while the thesis says the number is bounded by evidence, not architecture.

Direction: a critical edition of a result. Central column carries the argument; an apparatus in the margin carries receipts, provenance and caveats.

• Colour encodes epistemic status. Evidence blue only for what you can check; frontier rose only for the two cells we do not win, and for our caveats. Rose is the colour of honesty, not of error. Verified: rose 6.0:1, blue 8.4:1, ink 18.9:1 on paper. Marginalia moves off subtle (4.59:1, uncomfortable at 13px) onto muted (7.1:1).
• Two typographic registers, so the reader knows which object they hold: serif for the book, mono for data (GO:0006355 is a code and should look like one), sans only inside /instrument/*. Measure in ch with hyphens: auto, or the column breaks in German.
• The hero is the nine-cell grid, typeset as a table, with the two BP cells we lose set in rose. Opening with what we lose is the risk this design takes, and it is the right one: an honest frontier is the most characteristic thing in this subject's world. One motion only: three rows arriving in order, removed under prefers-reduced-motion.
• The signature: a footnote you pull. The marker expands the margin note in place into the receipt, the script and the POST /jobs payload. The action is a hairline-underlined link, not a filled button. After dispatch the marker gains = if the number reproduces, a rose ≠ if it diverges. The footnote is the reproduction — FR-1, in the register of scholarship.
• Every evidence table carries a frame stamp on its caption. A table without one is a bug.
• Removed: the orbs, the blur, the pulsing dot, the rounded hero, the logo on book pages.
