Herbarium Specimen Sheet

### Color Palette

All colors use `oklch()` for perceptual uniformity. Neutrals are cool-tinted (hue 250) to evoke archival fog, with warm accents (hue 80) for aged paper and tape.

### Typography

Four font families create the full herbarium voice:

| Role | Font | Weights | Usage |
|------|------|---------|-------|
| Display | Crimson Text | 600, 700 | Section headings, stamp institution names |
| Body | EB Garamond | 400, 500, 600 | Descriptions, taxonomy values, prose |
| Data | IBM Plex Mono | 300, 400, 500, 600 | Accession numbers, coordinates, labels |
| Field Notes | Caveat | 400, 500, 600 | Handwritten annotations, subheadings |

**Type Scale:**
- Section heading: Crimson Text 28px / 600
- Taxonomy value: EB Garamond 20px / 500
- Body text: EB Garamond 17px / 400, line-height 1.6
- Data label: IBM Plex Mono 11px / 500, uppercase, letter-spacing 0.1em
- Field annotation: Caveat 18px / 400, rotated -1.5deg to +2deg
- Micro label: IBM Plex Mono 9px / 500, uppercase, letter-spacing 0.15em

### Spacing Grid

Base unit: 4px. Generous vertical rhythm between sections, tighter within data groups.

- Section padding: 60px vertical
- Container gutters: 40px horizontal
- Field grid gap: 12px vertical, 24px horizontal
- Card gap: 24px–30px
- Label-to-value: 4px

### Border System

| Context | Style |
|---------|-------|
| Section dividers | 1px solid `--specimen-border` |
| Collection card | 2px solid `--specimen-border` |
| Institutional stamp | 3px solid `--specimen-stamp-red` |
| Data separators | 1px dashed `--specimen-border` |
| Key couplet dividers | 1px dotted `--specimen-border` |
| Taxonomy ladder | 1px dashed vertical line |

**Border-radius: 0px globally.** No exceptions. Herbarium sheets are cut paper — every edge is sharp.
