+# Brand Decisions v1 — Follow-up #1: Display Font Cyrillic Gap
+
+Date: 2026-05-17
+Open against: **D-05** (Type pairing)
+Owner: **Design team** (per D-05 OWNER row)
+Blocker for: Plan 01-12 (Design Integration) planner spawn; Plan 01-10 welcome
+hero text rendering

+
+## What was picked (D-05)
+
+A · Newsreader + IBM Plex Sans + IBM Plex Mono
+
+## What engineering research found
+
+Engineering research (`.planning/phases/01-stabilize-video-pipeline/01-12-RESEARCH.md`,
+commit `3df2750`, §1) verified Newsreader's glyph coverage via two independent
+sources:
+
+1. **The Decision Brief's own embedded `@font-face` declarations** — subsets shipped: `latin` / `latin-ext` / `vietnamese`
+2. **Production Type's `productiontype/Newsreader` repo README** — quote: "Google Fonts Latin Plus glyph set"
+
+**Newsreader ships NO Cyrillic glyphs.** Under the current D-05 pick, Russian
+display text (welcome hero, tagline, any future display-register H1/H2) would
+silently fall through `--mks-font-display` to `Iowan Old Style → Times New
+Roman → serif`.
+
+Mokosh's audience is Russian operators primary; display text in Russian is the
+default case, not the exception. This is therefore not a corner case — it
+affects the default rendering path.
+
+## Options for designer to pick
+
+| Option | Approach | Trade-off |
+|---|---|---|
+| **R1** | Keep Newsreader for Latin; add Cyrillic-capable OFL serif as fallback in `--mks-font-display` chain (e.g. `'Newsreader', 'PT Serif', serif`) | Preserves Newsreader aesthetic for Latin/English. Mixed-glyph paragraphs (Latin tagline + RU phrase together, or English wordmark + Russian subtitle) render in two different serifs — visually disharmonious |
+| **R2** | Substitute Newsreader entirely with a Cyrillic-native OFL serif | Unified rendering across all locales. Departs from designer's Newsreader pick — the aesthetic match for the Loom palette + 2×2 weave mark may or may not transfer |
+| **R3** | Other — designer proposes alternative (different display family / drop display register in favor of unified Plex Sans / use unicode-range `@font-face` to scope Newsreader to Latin-only and load second face for Cyrillic without disharmony / etc.) | Designer's call |
+| **R4** | Keep Newsreader as-is, accept Cyrillic fallback to `Iowan Old Style → Times New Roman` | If the operator-facing aesthetic for RU is intentional or acceptable |
+
+## Candidate Cyrillic-capable OFL serifs (research §1 R1)
+
+| Family | Provenance | Aesthetic notes |
+|---|---|---|
+| **PT Serif** | ParaType (Russian foundry) | Designed specifically for Russian government use; excellent Cyrillic coverage; visually pairs well with IBM Plex Sans |
+| **EB Garamond** | OFL recreation of classic Garamond | Classical, formal feel; full Cyrillic |
+| **Lora** | OFL contemporary serif | Modern, slightly humanist; Cyrillic native |
+| **Source Serif** | Adobe OFL | Clean, neutral; Cyrillic via subset |
+
+## What we need back from designer
+
+A one-line reply is enough:
+
+- `"R1, fallback chain Newsreader → PT Serif"` (or another fallback)
+- `"R2, substitute with PT Serif"` (or another family)
+- `"R3: <your proposal>"`
+- `"R4, accept the Iowan/Times fallback for Cyrillic"`
+
+You can also reply on the Decision Brief HTML, send updated `tokens.css`, a
+Figma link, or just a Slack/Russian-voice-memo — anything readable.
+
+## What's paused until designer responds
+
+- Plan 01-12 (Design Integration) planner spawn — needs final `--mks-font-display` token value to write the WOFF2 bundling task spec
+- Plan 01-10 (welcome tab) execution — welcome hero uses display register, needs the resolved font
+- The 8 i18n copy strings work (Brief §02) — depends on whether display-register copy lands in the welcome hero (most candidates do)
+
+Plan 01-11 (Puppeteer UAT harness) runs in parallel — non-overlapping surface; not affected.
