Typeset

Context: this sub-skill is one lens of the broader ui-craft skill. If the ui-craft skill is also installed, read its SKILL.md first for Discovery + Anti-Slop + Craft Test, then apply the specific lens below.

Typeset the UI at the target the user described. Load the ui-craft skill and read references/typography.md.

Note: typeset is knob-agnostic — typography rules (no ALL CAPS on headings, tracking-tight ≥24px, one body font, etc.) are not tunable.

Apply, in order:

1. Font inventory — what's loaded? If Inter is the default choice with no reason, ask before accepting it (Inter is the #1 AI-tell). Good alternatives: Geist, DM Sans, Plus Jakarta Sans, system stack. One body font, optionally one display font. Never three.

1. Scale — is there a scale or are sizes ad hoc? Anchor to a modular scale (1.125 / 1.2 / 1.25). Sizes: 12 / 14 / 16 / 20 / 24 / 32 / 48 / 64 / 72. No 13px / 15px / 17px one-offs unless optical.

1. Tracking (letter-spacing):

• ≥ 24px → tracking-tight (-0.02em) or tighter for 40px+
• 14-20px body → default
• 11-13px category labels → tracking-wide (+0.06em) + uppercase IS allowed here (the one exception)
• Never ALL CAPS on headings, nav, buttons, tables

1. Leading (line-height):

• Headings: 1.05-1.15
• Body: 1.5-1.65
• UI (buttons, labels): 1.2-1.3

1. Weight hierarchy — pick 2-3 weights max. Common: 400 body, 500 UI/labels, 600-700 headings. Never load 9 weights "just in case".

1. Micro-typography (the compound details):

• tabular-nums on every number you align (tables, stats, timestamps, prices)
• text-wrap: balance on headlines, text-wrap: pretty on body
• Curly quotes (' / "), em dashes (—), en dashes (–), no double hyphens
•   in brand names, between number + unit, and before final short words in headlines
• Real apostrophes in contractions
• font-feature-settings or font-variant-* for opt-in features (ligatures, ss01, fractions)
• Straight prime marks (′, ″) for units, not quotes

1. Hierarchy check — can you tell primary / secondary / tertiary at a glance? If every line has the same weight or size, collapse or amplify.

Amplifying hierarchy

If the UI is technically correct but forgettable, use typography as the weapon. Pick ONE element to carry signature (never two); boldness is typography, not color or decoration:

1. Hero headline — push size to 80-120px, weight to 700-800, tracking to -0.04em. Tight leading (0.95-1.0).
2. Hierarchy jump — widen the gap between H1 and body. If H1 is 32px and body is 16px, the UI is whispering; if H1 is 48px+, the ratio reads. Compress or expand the range deliberately.
3. Micro-motif — one custom detail that repeats: a hand-drawn underline, numeric counters (01, 02), an asymmetric supporting element, a distinctive list marker.

Knob gating for amplification (CRAFT_LEVEL):

• ≤ 4 — skip. Boldness is a craft layer, not a baseline.
• 5-7 — apply the type amplification only. No signature motif unless asked.
• 8+ — type amplification + one signature detail (owned by /polish).

Pre-check: if an accent is already overused or hierarchy is already loud, you don't have a tameness problem — you have a noise problem. Route to /distill (cut) or /colorize (reduce accents) instead.

Output: edit code directly. Print the Review Format table. Call out the single highest-impact change (usually: "font choice" or "tracking-tight on hero").
