feat: fill-manifest-sha256.ps1 + CERT local font-face first

Hash helper for DOWNLOADS-MANIFEST; certificate.html prefers fonts/*.woff2 when present.

CERT self-host fonts (printit.verae.ai)

Drop-in woff2 directory for the CERT-01 web viewer (../certificate.html).

certificate.html probes this folder at load time. If any planned .woff2 validates (woff2 magic wOF2), it injects local @font-face and skips the Google Fonts CDN. If none are present, it loads CDN Fraunces + JetBrains Mono. Binaries are not committed — only .gitkeep keeps the path in git. Do not download or commit proprietary fonts.

Install

Place OFL-licensed files next to this README (no proprietary fonts):

# From this directory (site/printit.verae.ai/fonts/)
cp /path/to/fraunces-opsz-wght-700.woff2 .
cp /path/to/fraunces-opsz-wght-600.woff2 .   # optional weight 600
cp /path/to/jetbrains-mono-500.woff2 .      # optional mono
cp /path/to/OFL.txt .                        # required beside binaries

./fetch-fonts.example.sh --check             # exit 0 when required set present

Deploy with the static site (rsync to /var/www/printit.verae.ai/ — see parent README.md). No HTML edit is required: the viewer auto-selects local vs CDN.

Usage

# No woff2 yet → certificate.html uses Google Fonts CDN Fraunces
open ../certificate.html

# After drop-in → local @font-face only (CDN not requested)
./fetch-fonts.example.sh --check && open ../certificate.html
# Smoke offline: block fonts.googleapis.com / fonts.gstatic.com;
# title must still render Fraunces from local woff2 (or Georgia if missing).

How drop-in works:

Obtain OFL-licensed Fraunces (and optional JetBrains Mono) as woff2 from upstream or a subsetted build (title glyphs only is enough for CERT).
Name files exactly as in Planned filenames.
Commit OFL.txt / LICENSE next to the binaries (keep copyright notices).
Open certificate.html — head script HEADs each candidate, checks woff2 magic (avoids Caddy try_files HTML false-positives), injects @font-face for hits, otherwise appends the CDN <link>.
Keep the Georgia / Times New Roman / serif stack as final fallback in CSS.

Do not uncomment network fetches in fetch-fonts.example.sh until license review. This tree must not ship proprietary font files.

Background

Surface	Fonts today	Offline fallback
`certificate.html` title	Local `fonts/.woff2` if present, else Fraunces* CDN	Georgia / Times New Roman / serif
Mono digests	Local mono woff2 if present, else JetBrains Mono CDN	ui-monospace / SF Mono / Menlo
UI kit (`verae-ui-kit.css`)	Inter + Material Symbols Rounded CDN	system stacks in `brand/tokens.css`
Issued PDF (`internal/pdfcert`)	System / library serif — not Fraunces embed	N/A (separate from web)

Design source of truth: verae-2026-design/ui-designs/src/html/CERT-01.html (tokens --font-serif: 'Fraunces'; design-kit src/fonts/ ships Cantarell + Material Symbols TTF only — no Fraunces binary in-repo yet).

Not claimed: full CERT-01.html pixel match, PDF Fraunces embed, or production binaries in git.

Planned filenames

fonts/
  README.md                 (this file)
  .gitkeep
  fetch-fonts.example.sh    # curl placeholders; no download until uncommented
  fraunces-opsz-wght-600.woff2   # variable or static; opsz + weight 600
  fraunces-opsz-wght-700.woff2   # weight 700 (title)
  jetbrains-mono-500.woff2      # optional; digests already have mono stack
  OFL.txt / LICENSE             # required license text beside binaries

Exact names must stay stable once wired so deploys and the head probe match.

Fetch scaffold

fetch-fonts.example.sh — example only. Comment-only upstream URLs (google/fonts OFL trees). Does not curl until an operator uncomments a pinned-commit block after license review.

./fetch-fonts.example.sh          # prints instructions; no network
./fetch-fonts.example.sh --check  # exit 1 until woff2 + OFL.txt present

Out of scope

Item	Owner / later
PDF CERT Fraunces embed	I7 done: pdfcert/build.mjs note + test — Times/Helvetica only until embed lands
Inter / Material Symbols self-host for whole site	optional; CERT title is OPEN-ISSUES #7 residual
Cantarell from design-kit TTFs	GNOME mock only; not required for CERT-01 web title
Pixel-perfect CERT-01.html match	Still later (OPEN-ISSUES Advanced)

Status

Step	State
Placeholder dir + this plan	Done (L7)
`fetch-fonts.example.sh` placeholders	Done (TODO-7 A7) — no binaries fetched
Web cert spacing toward CERT-01	Closer — not full pixel
Local-first `@font-face` else CDN	Done — `certificate.html` probes `fonts/*.woff2`
Drop-in docs (this README)	Done
woff2 binaries + LICENSE in git	Not started — operator drop-in only
Pixel match / PDF embed claim	Not started — do not claim

Contributing

Questions: Verae eng / printit site owners. PRs that add OFL woff2 + OFL.txt with stable planned names are welcome. PRs that vendor proprietary fonts or strip copyright notices will be rejected. Do not enable the example fetch script in CI.

License

Font binaries, when added, remain under their upstream licenses (typically SIL Open Font License 1.1 for Fraunces and JetBrains Mono). Ship OFL.txt beside any binary. This directory does not re-license font files.
