Korean Hero / Large-Display Typography Port

Date: 2026-07-08

Kind: SoT reinforcement + downstream port (dev-frontend korea-2026.md + anti-slop.md)

User flagged that oversized bold Korean heroes read as slop specifically in

Hangul (shown on the GYEOL studio mockup: clamp(..., 10rem) / weight 700 /

line-height: 0.9). Two GPT-5.5 explorers researched how Toss and other premium

Korean services handle hero typography, with Tier-2 proof (one lane measured

live pages via Playwright computed style).

Premium Korean services size Korean heroes ~56-72px desktop / ~26-40px

mobile, weight 700 (not 900), line-height 1.25-1.4 (not 0.9), with

word-break: keep-all and manual phrase breaks. 900 shows up on English

display / short brand phrases, not long Hangul. Huge bold Hangul reads as a

heavy graphic mass because each syllable is a dense square block with little

ascender/descender rhythm (Typotheque, Morisawa). Measured: Toss home

66px/700/lh1.4, Toss team 72px/700/lh1.3, Daangn 64px/700/lh1.31, Kakao

70px/700/lh1.27, Woowa Korean 40px/700 (its 900 is English), Naver 32px/600,

Musinsa 20px/600.

Target	Files	Status
SoT	`pabcd_initiative/.../korea-2026.md`, `anti-slop.md`	Done — added "Korean Hero / Large Display Type" subsection + slop signal
cli-jaw	`cli-jaw-skills/.../korea-2026.md`, `anti-slop.md`	Done — same block (Korean-hero block diff-matches SoT)
codexclaw	`codexclaw/plugins/codexclaw/skills/dev-frontend/.../korea-2026.md`, `anti-slop.md`	Done — same block
jawcode	—	N/A (no dev-frontend skill)

Note: korea-2026.md and anti-slop.md were already divergent between SoT and

cli-jaw before this change, so the port adds the SAME new block to each rather

than byte-syncing whole files. The new Korean-hero block is diff-identical

across SoT and cli-jaw.

The GYEOL studio hero was refixed to the restrained pattern (verified via

Playwright computed style): desktop 74.9px / 700 / line-height 1.16 / keep-all,

mobile 33.6px / 700 / lh 1.16, down from ~160px / 700 / lh 0.9. The hero now

leans on whitespace + imagery + supporting copy instead of a giant Hangul wall.
