## Description
Font loading is one of the largest contributors to Largest Contentful Paint (LCP)
on real websites. Peakspire Font Loading Optimizer applies the three highest-impact
font fixes, built from hands-on Core Web Vitals engineering on production sites:
1. **Preload local WOFF2 fonts** – Scans your enqueued stylesheets for locally hosted
WOFF2 files and adds `` tags, capped at 4 fonts. Preloaded
fonts arrive before the browser discovers them inside CSS files, removing the font
round-trip from the critical path.
2. **Adds `font-display: swap` to eligible inline `@font-face` rules** – Rules that
already declare an explicit `optional`, `block`, `fallback`, or `auto` value are
never touched. Rules without a descriptor get `swap`, so text renders immediately
with the fallback font instead of sitting invisible while web fonts download.
3. **Remove external Google Fonts (optional)** – Dequeues all fonts.googleapis.com
requests for sites that have self-hosted their fonts.
4. **Remove dashicons for visitors (optional)** – Dequeues the dashicons stylesheet
for logged-out visitors, saving a render-blocking request most themes never use
on the front end.
Everything is front-end only and safe to use alongside caching plugins (WP Rocket,
LiteSpeed Cache, W3 Total Cache, etc.).
#### Why only local fonts are preloaded
Cross-origin font preloads waste bandwidth when the crossorigin fetch does not match
the stylesheet fetch. This plugin deliberately preloads only same-host WOFF2 files,
the safe default for virtually all themes that self-host fonts.
## Installation
1. Upload the `peakspire-font-loading` folder to `/wp-content/plugins/`, or install
via the Plugins screen.
2. Activate the plugin.
3. Open Settings Peakspire Font Loading Optimizer. Preload and font-display are on
by default; both are recommended.
## FAQ
### Which fonts does this preload?
WOFF2 files hosted on your own domain that are referenced from enqueued external
stylesheets, up to a static maximum of 4 per page. Fonts declared inline in the
HTML head are deliberately NOT preloaded: the browser already discovers those at
parse time, so preloading them adds bandwidth cost without benefit (measured: a
~0.9s LCP regression on an inline-declaring theme before this rule was enforced).
This is a deliberate simplicity tradeoff: the plugin does not measure per-page font
relevance (paid performance suites do). For most sites with 2-4 font families, the
cap is the right size.
### Does this replace a font-localization plugin like OMGF?
No – it complements one. Localization plugins handle fonts sourced from Google/Bunny
CDNs. This plugin handles the other half: the fonts your theme or builder already
bundles locally. Use both if you have both.
### Does this work with caching plugins?
Yes. All changes are front-end output (preload tags and CSS descriptor injection).
Nothing modifies your theme files or cache behavior.
### Which fonts get preloaded?
Only WOFF2 files hosted on your own domain that are referenced from your enqueued
stylesheets, up to a maximum of 4. Preloading more fonts typically hurts more than
it helps.
### What if my fonts come from Google Fonts?
Enable the “Remove external Google Fonts” option only after self-hosting your fonts.
Sites not ready for that step should leave it off.
### Is the font-display change safe for my design?
font-display: swap shows the fallback font until your web font loads, then swaps.
It is the descriptor Google recommends and the default in most modern themes.

## Changelog
#### 1.0.3
* Discovery prioritization: same-host stylesheets scanned first; CDN-hosted stylesheets
no longer consume scan slots (they cannot yield same-host WOFF2 URLs)
* Real-theme tested on Twenty Twenty-Four: external CSS fonts correctly preloaded,
inline declarations correctly skipped
* PHP 7.4 literal execution verified (Docker php:7.4-cli, lint + token scan)
#### 1.0.2
* Security hardening: SSRF defense (private/loopback/link-local IP deny-list before
fetch), cache-hit re-validation (same-host + is_string on every cached entry),
corrupt-lock-value recovery (stale-reclaimable, not live-forever)
* Availability: preg_replace NULL guard on backtrack-limit exhaustion (never blanks
a page)
* CSS correctness: @font-face rewrite scoped to
* Measured: zero LCP regression on inline-font themes; preload timing verified
on external-CSS pages
#### 1.0.0
* Initial release: WOFF2 preload discovery, global font-display:swap injection,
optional Google Fonts removal, optional dashicons removal for guests.
