 ### Docs
 - Update the README logo (EN + 14 translated READMEs) from `logo-wordmark.png` to the new `fa_updated_full.svg` wordmark served on befailproof.ai (#387).
+- Add a Bitcount Prop Single font template under `templates/bitcount-font/` (next/font loader, framework-agnostic CSS with tunable knobs, and a `preview.html` demo page) capturing the befailproof.ai title treatment for reuse (#390).

+# Bitcount Prop Single — font template
+
+The title / wordmark treatment from **befailproof.ai**, packaged so you can drop
+the exact same look into any project.
+
+**Fine-tuned instance:** `font-variation-settings: "wght" 417, "ELSH" 55` (slnt 0),
+horizontally squished `scaleX(0.9)`, `letter-spacing: 0.08em`, lowercase. All four
+are exposed as knobs in `bitcount.css`.
+
+## Files
+- `bitcount.css` — the reusable `.bitcount-title` class + tunable `:root` knobs, plus a self-host `@font-face`. Framework-agnostic.
+- `fonts.ts.example` — Next.js `next/font/google` loader (rename to `fonts.ts`). Matches how befailproof.ai loads it.
+
+## Use it
+
+### Next.js
+1. Rename `fonts.ts.example` → `fonts.ts`, import `bitcount` in your root layout, add `bitcount.variable` to `<html>`.
+2. Import `bitcount.css` and **delete its `@font-face` block** (next/font already provides `--font-bitcount`).
+3. Add `class="bitcount-title"` to headings / wordmarks.
+
+### Anywhere else
+1. Self-host (most reliable): download the Bitcount Prop Single **variable** woff2 and drop it next to `bitcount.css` as `bitcount-prop-single.woff2`. Or use the Google Fonts CDN `@import` — see the comment in the CSS, and verify the `ELSH` range.
+2. Import `bitcount.css`, add `class="bitcount-title"`.
+
+## Tuning knobs (`:root` in `bitcount.css`)
+| Variable | Default | Effect |
+|---|---|---|
+| `--title-scale` | `0.9` | title size multiplier |
+| `--title-squish` | `0.9` | horizontal `scaleX` squish |
+| `--title-tracking` | `0.08em` | letter-spacing |
+
+To re-tune the glyph shape itself, change `"wght"` / `"ELSH"` in the
+`font-variation-settings` of `.bitcount-title`.
+
+## Provenance
+Recovered from the befailproof.ai web platform (PR #374). Axis values verified
+against the final iteration of that work (earlier passes used wght 413/414 and
+ELSH 51.4 before settling on **417 / 55**). The exact `--title-scale` application
+and the fallback stack are reconstructed from the session — adapt to your project.

+   Fine-tuned instance: wght 417, ELSH 55  (slnt left at default 0)
+   The ELSH "Element Shape" axis is kept variable so it can be tuned.

+   (A) Next.js   -> use fonts.ts.example (next/font/google). It sets
+                   --font-bitcount for you. DELETE the @font-face below.
+   (B) Self-host -> drop the variable woff2 next to this file and keep
+                   the @font-face below (most reliable; ELSH stays variable).
+   (C) Google CDN-> replace @font-face with:
+       @import url('https://fonts.googleapis.com/css2?family=Bitcount+Prop+Single:ELSH,wght@0..100,100..900&display=swap');
+       NOTE: this URL is verified working (ELSH 0..100, wght 100..900). Adjust ranges if you need others.
