summary
Reglet is the letterpress review-desk language. A reglet is the thin strip a printer locks between lines to hold the measure true; Reglet makes that strip the interface. Its one ownable idea is the folio rail — a thick bone galley rule that runs down the left margin, numbering every section, capping it with a rule, and ticking one saffron signal where a verdict needs attention. It reinterprets an institutional editorial-review source, but moves it off the warm-paper red-black-white spread onto a warm-ink night desk, where a single saffron ink does all the signaling and scores are typeset, not animated.

Deliberate, like a page going to press. A primary key flips to a saffron offset on hover; a field gains a saffron inset focus bar. The settled, fully-set state renders with no JavaScript; reduced-motion shows it instantly.
rules
composition
Compose screens as a bound issue locked to a left-margin folio rail: a thick bone galley rule down the margin, each section opening with a running mono folio number, a condensed display heading, and a right-aligned meta label, capped by a rule. A dominant narrative column and a narrower evidence rail lock to the same measure. Panels are square 0-radius ink frames capped by a 3px bone rule — never floating cards, never a boxed-in pill nav.
hierarchy
Lead with one large condensed display score or title; build rank from scale, weight, rule thickness, and the single saffron tick — not from shadows. Serif body and mono metadata give a tri-level institutional voice.
density
Medium-dense to dense. Ledgers and evidence blocks may be compact, but every dense zone is buffered by measured whitespace bands and a visible cap rule, so the page reads as a research-journal issue, not a crowded console.
signature patterns
Run a thick bone galley rule down the left margin and open every major section with a running mono folio number, binding the page like an issue.Cap each section head (number / heading / meta) with a rule, and each major panel with a 3px bone top rule; let rules do the framing, never shadows.Signal state with one saffron ink only — a margin inset tick on a flagged module, a highlighter swipe on a single word, the hot segment in a meter.Render every quantity as a tick meter: a run of discrete square segments where lit cells count the value and one hot segment marks a peak or flag.Lock tables and metadata to one strict measure with mono tabular numerals, hairline separators, and alternating ink bands — no pills, no floating chips.

A 12-column desktop grid on an 8px base, framed by the folio rail in the left margin; key compositions run 8/4 or 7/5 column splits for editorial asymmetry, hard-aligned left and top.
breakpoints
Desktop 1280px+ keeps 12 columns and the full margin rail. Tablet 768px collapses to a stacked reading order keeping every folio number and cap rule. Mobile 390px folds the rail into the section head (the meta label wraps under the heading), reduces tables to key columns, and never overflows horizontally; the nav wraps, never spills.
whitespace
Large top margins and inter-section bands give institutional breathing room around dense content; the galley rail and cap rules measure the rhythm so whitespace reads as deliberate, not soft.
responsive
Shift from the multi-column margin-railed spread to a single stacked reading column while preserving folio numbers, cap rules, the saffron ticks, and the tri-level type at every breakpoint.

guidance
do
  • Open every section with a folio number on the margin rail and cap it with a rule.
  • Keep saffron a single signal — a margin tick, one highlighter swipe, a meter peak — never a wash or a background.
  • Lock tables and scores to one measure with mono tabular numerals so columns of figures line up.
  • Frame with the bone galley rule and hairlines; keep corners hard at 0 radius and let depth be the rule.
  • Pair condensed Archivo display with Spectral serif body and Spline Sans Mono metadata for a tri-level voice.
avoid
  • Do not default to warm paper or red-black-white; Reglet lives on a warm-ink night desk.
  • Do not flood areas with saffron — it loses its registration force.
  • Do not replace tick meters with smooth gradient bars or glossy charts.
  • Do not float pills and chips, box the nav into a widget, or nest cards.
  • Do not center everything symmetrically; the margin rail and editorial asymmetry are the point.

summary
Imagery uses the letterpress relief technique: subjects pressed hard into warm cotton-rag paper, value built from broken-ink dry-press texture and fine engraved hatching, in a strict two-ink registration with one small saffron spot accent. Heroes are full-bleed worked fields with a calm band of bare paper left open for the overlay.

# Reglet

## Philosophy

Reglet is the letterpress review-desk language. A reglet is the thin strip a printer locks between lines to hold the measure true; Reglet makes that strip the interface. Its one ownable idea is the folio rail — a thick bone galley rule that runs down the left margin, numbering every section, capping it with a rule, and ticking one saffron signal where a verdict needs attention. It reinterprets an institutional editorial-review source, but moves it off the warm-paper red-black-white spread onto a warm-ink night desk, where a single saffron ink does all the signaling and scores are typeset, not animated.

### Values

- Bind the page like an issue: every section is a numbered folio capped by a rule, not a floating card.
- Lock to the measure: tables, scores, and copy hold one column, with mono tabular numerals doing the alignment.
- Signal with one ink: saffron is a registration tick, a highlighter swipe, a meter peak — a spark, never a wash.
- Frame with rules, not shadows: a bone galley rule and a hairline do the structure; depth is the rule.
- Typeset the verdict: condensed display scores against serif copy and mono metadata — an institutional voice you trust.

### Anti-Values

- Rounded consumer-app softness, glass, or blurred translucency.
- Red-black-white on warm paper as a default editorial costume.
- Smooth gradient meters and glossy charts that hide a discrete reading.
- Floating pills and chips, boxed-in nav widgets, decorative gradients.
- Centered symmetry — Reglet depends on the asymmetric margin rail.

### Visual Character

- A thick bone galley rule runs down the left margin and every major section opens with a running mono folio number, so the screen reads as a bound issue rather than a stack of cards.
- Section heads are a folio — number, condensed display heading, and a right-aligned mono meta label — capped by a 1px rule; panels carry a 3px bone top rule.
- One saffron signal ink appears only as a margin inset tick on a flagged module, a highlighter swipe under a single headline word, and the hot segment in a meter.
- Quantities read as tick meters: a run of discrete square segments (lit, unlit, one hot) rather than a smooth bar.
- Tri-level type — Archivo condensed display for scores and titles, Spectral serif for body, Spline Sans Mono for folios, metadata, and tabular numerals — set on a warm press-bed ink ground with bone paper text.

## Rules

### Composition

Compose screens as a bound issue locked to a left-margin folio rail: a thick bone galley rule down the margin, each section opening with a running mono folio number, a condensed display heading, and a right-aligned meta label, capped by a rule. A dominant narrative column and a narrower evidence rail lock to the same measure. Panels are square 0-radius ink frames capped by a 3px bone rule — never floating cards, never a boxed-in pill nav.

- Cap each section head (number / heading / meta) with a rule, and each major panel with a 3px bone top rule; let rules do the framing, never shadows.

### Do

- Open every section with a folio number on the margin rail and cap it with a rule.
- Keep saffron a single signal — a margin tick, one highlighter swipe, a meter peak — never a wash or a background.
- Lock tables and scores to one measure with mono tabular numerals so columns of figures line up.
- Frame with the bone galley rule and hairlines; keep corners hard at 0 radius and let depth be the rule.
- Pair condensed Archivo display with Spectral serif body and Spline Sans Mono metadata for a tri-level voice.

### Don't

- Do not default to warm paper or red-black-white; Reglet lives on a warm-ink night desk.
- Do not flood areas with saffron — it loses its registration force.
- Do not replace tick meters with smooth gradient bars or glossy charts.
- Do not float pills and chips, box the nav into a widget, or nest cards.
- Do not center everything symmetrically; the margin rail and editorial asymmetry are the point.

### Accessibility

Body text is 17px bone on warm ink for high contrast; verdict state never relies on colour alone — a mono label (pass / hold / re-test) and a discrete tick count carry the reading. Every form control is explicitly styled with a saffron inset focus bar; the saffron and ink-blue accents stay sparks, never low-contrast text-on-text. Motion respects prefers-reduced-motion by showing the settled, fully-set state instantly.

## Imagery Direction

### Summary

Imagery uses the letterpress relief technique: subjects pressed hard into warm cotton-rag paper, value built from broken-ink dry-press texture and fine engraved hatching, in a strict two-ink registration with one small saffron spot accent. Heroes are full-bleed worked fields with a calm band of bare paper left open for the overlay.

### Subjects

- composing sticks and locked-up metal type on a press bed
- portraits and avatars as engraved relief prints
- single objects and instruments as print specimens
- skylines and architecture pressed into paper
- review-desk still lifes and tools

### Usage

Use full-bleed relief fields for heroes with the ink mass weighted to one side and bare paper left for the overlay; use centered single-subject print specimens for feature and avatar slots; keep empty-states mostly bare paper with one faint impression.

### Grid

A 12-column desktop grid on an 8px base, framed by the folio rail in the left margin; key compositions run 8/4 or 7/5 column splits for editorial asymmetry, hard-aligned left and top.

### Breakpoints

Desktop 1280px+ keeps 12 columns and the full margin rail. Tablet 768px collapses to a stacked reading order keeping every folio number and cap rule. Mobile 390px folds the rail into the section head (the meta label wraps under the heading), reduces tables to key columns, and never overflows horizontally; the nav wraps, never spills.

### Whitespace

Large top margins and inter-section bands give institutional breathing room around dense content; the galley rail and cap rules measure the rhythm so whitespace reads as deliberate, not soft.

### Responsive

Shift from the multi-column margin-railed spread to a single stacked reading column while preserving folio numbers, cap rules, the saffron ticks, and the tri-level type at every breakpoint.

## Components

### Composition

Compose screens as a bound issue locked to a left-margin folio rail: a thick bone galley rule down the margin, each section opening with a running mono folio number, a condensed display heading, and a right-aligned meta label, capped by a rule. A dominant narrative column and a narrower evidence rail lock to the same measure. Panels are square 0-radius ink frames capped by a 3px bone rule — never floating cards, never a boxed-in pill nav.

### Hierarchy

Lead with one large condensed display score or title; build rank from scale, weight, rule thickness, and the single saffron tick — not from shadows. Serif body and mono metadata give a tri-level institutional voice.

### Density

Medium-dense to dense. Ledgers and evidence blocks may be compact, but every dense zone is buffered by measured whitespace bands and a visible cap rule, so the page reads as a research-journal issue, not a crowded console.

### Signature Patterns

- Run a thick bone galley rule down the left margin and open every major section with a running mono folio number, binding the page like an issue.
- Cap each section head (number / heading / meta) with a rule, and each major panel with a 3px bone top rule; let rules do the framing, never shadows.
- Signal state with one saffron ink only — a margin inset tick on a flagged module, a highlighter swipe on a single word, the hot segment in a meter.
- Render every quantity as a tick meter: a run of discrete square segments where lit cells count the value and one hot segment marks a peak or flag.
- Lock tables and metadata to one strict measure with mono tabular numerals, hairline separators, and alternating ink bands — no pills, no floating chips.

When the target app uses shadcn/ui, copy DESIGN.md with shadcn instead of the plain DESIGN.md. It contains the same Katagami design-language source plus the shadcn/ui primitives, imports, theme variables, component recipes, and preview-shot guidance.

DESIGN.md with shadcn: `/language/en-019efd5b-cb01-7732-af35-b6cf65bed82c/DESIGN.with-shadcn.md`.

The shadcn page also exposes optional machine-readable files for automation, but the human-facing handoff is DESIGN.md with shadcn.

Install recommended primitives with `npx shadcn@latest add button card input textarea select dialog sheet tabs badge separator checkbox switch slider tooltip dropdown-menu table`.

Use these primitives in shadcn apps:
- button
- card
- input
- textarea
- select
- dialog
- sheet
- tabs
- badge
- separator
- checkbox
- switch
- slider
- tooltip
- dropdown-menu
- table

Implementation rule for agents: import shadcn primitives from `@/components/ui/*`, apply the generated CSS variables first, then compose the language-specific recipes from the companion MD. Katagami remains the source of truth; shadcn names are the implementation surface.

## Do's and Don'ts

- Do Open every section with a folio number on the margin rail and cap it with a rule.
- Do Keep saffron a single signal — a margin tick, one highlighter swipe, a meter peak — never a wash or a background.
- Do Lock tables and scores to one measure with mono tabular numerals so columns of figures line up.
- Do Frame with the bone galley rule and hairlines; keep corners hard at 0 radius and let depth be the rule.
- Do Pair condensed Archivo display with Spectral serif body and Spline Sans Mono metadata for a tri-level voice.
- Don't Do not default to warm paper or red-black-white; Reglet lives on a warm-ink night desk.
- Don't Do not flood areas with saffron — it loses its registration force.
- Don't Do not replace tick meters with smooth gradient bars or glossy charts.
- Don't Do not float pills and chips, box the nav into a widget, or nest cards.
- Don't Do not center everything symmetrically; the margin rail and editorial asymmetry are the point.

### Accessibility

Body text is 17px bone on warm ink for high contrast; verdict state never relies on colour alone — a mono label (pass / hold / re-test) and a discrete tick count carry the reading. Every form control is explicitly styled with a saffron inset focus bar; the saffron and ink-blue accents stay sparks, never low-contrast text-on-text. Motion respects prefers-reduced-motion by showing the settled, fully-set state instantly.

## Imagery Direction

### Pairs With

reglet-letterpress-rule

### Summary

Imagery uses the letterpress relief technique: subjects pressed hard into warm cotton-rag paper, value built from broken-ink dry-press texture and fine engraved hatching, in a strict two-ink registration with one small saffron spot accent. Heroes are full-bleed worked fields with a calm band of bare paper left open for the overlay.

### Subjects

- composing sticks and locked-up metal type on a press bed
- portraits and avatars as engraved relief prints
- single objects and instruments as print specimens
- skylines and architecture pressed into paper
- review-desk still lifes and tools

### Usage

Use full-bleed relief fields for heroes with the ink mass weighted to one side and bare paper left for the overlay; use centered single-subject print specimens for feature and avatar slots; keep empty-states mostly bare paper with one faint impression.
