Linked issues

Relates to Linear LSA-107 (design: history-page - Build History page). It does not close the issue: the Year by year section, the page content on DEV, SEO metadata and the manual QA are still open.

Design Overview

The two new section patterns for the About "History" page (/about/history/), built from the standalone prototype About History.html and the content doc 02-about-history.md.

• Section - Scroll Timeline: "The LightSpeed Journey" as nine milestone nodes (a mono year, a dot on a vertical line and a flat card). As the page scrolls, a glowing gradient line fills down the timeline and each node fades up and lights its dot. The last node is a dashed, tinted "future" card. The editor, no-JS and reduced-motion views show every node lit and the full line.
• Section - Stat Card Grid: "A Legacy of Open-Source Contribution" as four flat stat cards with figures in their own accent colours, above a closing line.
• Reuse first: the timeline cards reuse Card - Plain and the dots reuse the existing lightspeed/dot Icon block. The History page's Hero, Our History, FAQ and CTA reuse hero-split-proof, split-intro-text-pair, solutions-split-faq and homepage-cta with page-level copy edits, so they add no files.

Changes

• Scroll Timeline: patterns/sections/scroll-timeline.php, src/scss/structural/scroll-timeline.scss (compiled to assets/css/scroll-timeline.css) and assets/js/scroll-timeline.js. The SCSS owns only what JSON cannot express (the pseudo-element line, the scroll-driven fill, the dot's lit state, the reveal and the card hover). The year column width and the line position read one custom property.
• Stat Card Grid: patterns/sections/stat-card-grid.php, no SCSS. The first stat reads "Websites built and rebuilt", following the content doc's claims table.
• Gradient tokens: new gradient.accent-start and gradient.accent-end in theme.json (brand-600 to cta-800) and styles/dark.json (brand-400 to cta-500). All four pairings are at least 3:1 against their canvas.
• Loading: inc/animations.php registers the scroll-timeline bundle (loads on /about/history/ and wherever the pattern renders) and enqueues the script through render_block, as the FAQ and contents-rail scripts do. functions.php adds the editor stylesheet and package.json adds the build entries.
• Editor fix: the editor makes every block position: relative, which beat the dot rule, so the dot selector uses three classes and a z-index. Editor and front end now give the same geometry.
• Homepage CTA button fix: the secondary button's no-arrow rule in src/scss/structural/homepage-cta.scss had the same specificity as the shared outline arrow, so whichever stylesheet loaded last won, and the arrow box showed (and clipped longer labels). The rules are now scoped under .ls-homepage-cta. This also corrects the homepage "Send a brief first" button.

Scope and exclusions

• Year by year (core details grid with "Expand all") is the next PR in the stack.
• Does not change the Hero, Our History, FAQ or CTA patterns beyond the CTA button fix above.
• Review size: 13 files (including CHANGELOG.md), 542 added and 6 removed lines against develop. This is over the preferred 400 lines but under 800. assets/css/scroll-timeline.css and assets/css/homepage-cta.css are compiled output (3 added or changed lines between them).

Screenshots / video

None attached. The timeline spacing was measured on the local site at 1440px against the prototype's CSS values (year column, dot to card, card padding, node gap), all within 2px. The editor markup was inspected after the dot fix.

Accessibility / performance notes

• Hidden and unlit states apply only once the script adds is-enhanced, so the timeline is fully visible without JS, in the editor and with prefers-reduced-motion. The script skips itself under reduced motion.
• The script uses an IntersectionObserver and a passive, requestAnimationFrame-throttled scroll listener. A node already scrolled past (anchor link, reload mid-page) still shows.
• Each node is an article because core list items cannot hold headings; the dot is decorative.
• Known: a scan that starts mid-fade can report contrast failures for the half-transparent text. The standing accessibility scan did this intermittently on the local site; the scan helper in tests/helpers/accessibility.ts now waits for transitions to finish (added in design: history-page - Add the Details Card Grid pattern for Year by year (LSA-107) #133, which is stacked on this PR), and the scan passed in both modes on the stack.

Testing

• npm run schema:validate and npm run lint:json pass
• npm run security:scan passes
• npm run patterns:escape reports nothing for the new patterns
• npm run build:css leaves no diff
• npm run theme:validate completes with warnings only
• php -l and phpcs pass for both patterns, inc/animations.php and functions.php
• Front end, 1440px: nine nodes, the line fills as you scroll, the dots sit on the line and the cards share one left edge
• Block editor: all nine dots are absolutely positioned on the line and the cards align with the front end
• Homepage CTA secondary button has no arrow box on /about/history/ and on the homepage
• CodeRabbit CLI review run (see below)
• Playwright standing suite plus the mobile-menu spec, run on the stacked design: history-page - Add the scroll timeline and stat card grid patterns (LSA-107) #132 + design: history-page - Add the Details Card Grid pattern for Year by year (LSA-107) #133 branch (the combined History page) with SINGLE_PAGE_URL on /about/history/, once in dark mode and once in light mode (page background confirmed each time) across Chromium, WebKit, Mobile Chrome, Mobile Safari and Tablet: 128 passed, 26 skipped, none failed in each mode (Firefox is not installed locally)
• Dark and light mode visual checks on desktop, tablet and mobile, done by the maintainer
• Screen reader tested
• History page on DEV after deploy

CodeRabbit CLI findings, not applied: (1) a guard for a zero-height timeline in the script, valid but trivial; (2) the stat label "GNU Public License" follows the content doc's wording; (3) the lightspeed/dot Icon block's WordPress minimum, which the existing patterns already use the same way.

Stack

• Position: PR 1 of 2

📝 Walkthrough

The PR adds localized History timeline and statistic-card patterns. It adds timeline styling, conditional scroll enhancement, gradient tokens, editor integration, and scoped homepage CTA outline-button rules.

Changes: History page patterns

Layer / File(s)	Summary
Timeline pattern and presentation patterns/sections/scroll-timeline.php, src/scss/structural/scroll-timeline.scss, assets/css/scroll-timeline.css, theme.json, styles/dark.json, package.json, functions.php, CHANGELOG.md	The pattern renders localized milestones, including a future milestone. Timeline styles define progress, reveal states, responsive layout, and reduced-motion behavior. Theme settings add gradient endpoints, and the CSS build and editor stylesheet include the timeline styles.
Conditional scroll enhancement inc/animations.php, assets/js/scroll-timeline.js	Rendered timeline blocks trigger deferred script loading. The script reveals nodes and updates scroll progress unless reduced motion is requested.
Stat-card section pattern patterns/sections/stat-card-grid.php	The pattern defines four localized statistics and renders them in a responsive card grid with introductory and closing text.

Homepage CTA styles

Layer / File(s)	Summary
Scope CTA outline-button rules src/scss/structural/homepage-cta.scss, assets/css/homepage-cta.css, CHANGELOG.md	The outline-button selector now requires the .ls-homepage-cta ancestor. This scopes arrow-removal and padding rules to the CTA component.

- Around line 22-25: Adjust the IntersectionObserver configuration in the scroll
reveal setup to include a bottom root margin of -10% while preserving
REVEAL_THRESHOLD, so tall nodes can trigger before reaching the full visibility
threshold. Keep the existing is-in class addition and observer.unobserve
behavior unchanged.

Review comments at @patterns/sections/scroll-timeline.php:
- Line 53: Update the year entries in the relevant section, including the nodes
around the 2022–2023 and 2003/2027 values, to avoid en-dash year ranges and use
a single year string per node. Remove translation wrappers for pure numeric
years, or replace them with _x() and an appropriate translator context for
non-numeric labels such as “2027 & Beyond.”
