* feat(design-systems): integrate kami as editorial paper system + deck starter
- Add design-systems/kami/DESIGN.md adapting kami's tokens, ten invariants,
and type/color/component rules into the OD DESIGN.md spec. Lands under a
new "Editorial & Print" category in the picker.
- Add templates/kami-deck.html: a kami-flavored variant of deck-framework.html
(parchment canvas, ink-blue accent, single-weight serif) with five demo
slides — cover, agenda, metric row, two-column body+pull-quote, closing —
so it doubles as a worked example for slide and prototype work.
- Update design-systems/README.md and README.md to list and credit kami
(MIT, tw93/kami).
- Update apps/web/src/i18n/content.ts so the i18n coverage test passes:
add the German summary for 'kami' and the 'Editorial & Print' category.
* docs(design-systems/kami): address PR #226 review notes
Five P3 polish edits from @lefarcen's review (LGTM, non-blocking):
1. Add a "When to swap the stack" subsection in §3 spelling out how the
three CJK font stacks combine: set the dominant-language stack on
:root, scope per-section overrides for mixed-language artifacts,
never chain all three families inside one font-family declaration.
2. Reframe the brand as "kami / 紙 / 纸" so the system reads as
co-designed across EN, zh-CN, and ja from the start, not Japan-centric
with i18n bolted on. Title and §1 lede updated.
3. Reconcile the pt → px ratios into one table at the top of §3
"Hierarchy": print pt × ~1.33 for page artifacts, × 1.6 for slide
macro tokens, × 0.6 for slide micro tokens. Drop the duplicate
ratio bullets from §5 "Slides".
4. Keep the soft tag-brush gradient exception but make it real: add
the .tag.brush CSS + an inline <span class="tag brush"> example
in §4, and surface it once on slide 04 of the kami deck so agents
see exactly when the carve-out applies.
5. Add a "Tabular-nums contexts" subsection in §3 enumerating every
place numbers should opt into tabular-nums (metrics, footers,
section numbers, dates, financial tables, KPI grids, version
numbers, side-by-side comparisons) — and the rule for when not to
(single numbers in running prose).
