The agent manifest. Start here.
Seven registers, two type families, eight surfaces, and print geometry that goes down to the thickness of a hardcover spine.
The loader resolves its own URL, so it works from the root of a project, a subfolder, or a copy bundled inside a single HTML file — without being edited.
<script src="…/ds-base.js"></script>
<html data-register="daylight" data-surface="web">
Registers and surfaces are orthogonal — any register on any surface. Nothing else in the document changes: palette, rules, grain blend mode and photographic grade all follow.
Prefer a local copy? Take the folder whole; nothing in it points outside itself. INSTALL.md
Every path in the system, grouped and sized. One fetch and you know what exists.
Each is a complete semantic palette, not a skin. Set one on
<html data-register>. Dark pages use --panel /
--panel-ink, never --ink / --paper,
which invert. Gold is a mark, never a fill.
| register | paper | ink | gold | blend |
|---|
Specimen cards for each, plus grades, type, spacing, brand and print, live in guidelines/ — 30 of them.
If a human would read it aloud, it is serif. Cormorant Garamond carries masthead, display, deck, body, captions and figures. Manrope carries only furniture the reader ignores — kickers, corner tags, folios, table heads — always uppercase, always tracked.
Headlines are whispered: weight 300 above 40px, never bold. Body sits at
16.5px / 1.72 on a 54ch measure, justified, hyphenated.
Everything scales off cqi, not vw.
Screen is a scaled view of the same canvas. tokens/print.css
carries twelve trims, so nobody is ever asked for a page size — and the
hardcover maths is already in there.
--trim-hardcover-w/h. Royal, the same block as the royal trim.
--board-thickness, with an 8 mm --hinge-gap and a 15 mm --wrap-turnin.
Cream 50 · white 50 · white 60 · coated 80. Pages × caliper = spine width.
Nothing meaningful inside 5 mm of the trim. Crop marks 5 mm at a 3 mm offset.
Web is 150 dpi sRGB off the same source.
All in tokens/print.css.
A class on .spread. Start from a template rather than
inventing a layout — templates/book-volume/ and
templates/textbook-chapter/ are the two a book wants, and
ui_kits/issue-template/ is a complete 24-spread issue ready to
re-fill.
.cover .index .inhale .deep
.whole .plate .reflect .lexicon
.journey .steps .series .cited
.colophon
.cited — Works Cited — appears in every issue and is
never trimmed to fit. That is where a verified citation list lands.
