Put oss.cvoya.com back on cvoya.com's tokens

[savasp-agent]

The web repo's CLAUDE.md says this site "reuses this repo's cvoya.com design tokens; keep them visually in step when cvoya.com changes." It had drifted — and the drift was much larger than the container-width difference that prompted the look.

	cvoya.com	oss.cvoya.com (before)
Typeface	Libre Franklin	Inter
Body background	#f7f9fc (cool near-white)	#ffffff
Body ink	#1e2b41	#111111
--site-max	1080px	1040px
Container padding	clamp(1.25rem, 4vw, 2rem)	fixed 24px

The typeface and the ground colour are what a visitor actually notices. Crossing from cvoya.com to oss.cvoya.com read as landing on a different company's site.

What changed

Adopt cvoya.com's token vocabulary outright rather than approximate it — same names, same values (--ink / --ink-bright / --ink-muted, --ground / --surface, the hairlines, --face, --step-0, --site-max). The two surfaces now stay in step by construction rather than by memory. Fixing only --site-max would have closed the width gap while leaving the visible mismatch fully intact.

Knock-on adjustments so the borrowed tokens actually land:

• Container and nav gutters go fluid (clamp(1.25rem, 4vw, 2rem)), matching cvoya.com.
• The navbar's translucent fill is tinted to the ground it floats over (rgb(247 249 252 / 82%)), not to white.
• The hero glow becomes a white --surface wash on the tinted ground. The old navy wash was tuned for a pure-white page and goes muddy on a tinted one.
• .project:hover now lifts a row to white --surface (it previously lifted to #f7f8fb, which is invisible against the new ground).
• Two spots where the token remap flattened emphasis — .project-meta strong and the install code — were pushed back to --ink so they stay distinguishable from the muted text around them.

Also: a false claim

The Spring Voyage row read "Hosted service at spring.voyage." There is no hosted service — spring.voyage/hosted.html says "Self-hosting is the only way to run it; there is no hosted service," and cvoya.com says the same. Replaced with the BSL conversion date, which is what that meta slot carries for the other project.

Verification

• html-validate and stylelint both pass against the web repo's shared configs.
• Computed styles now match cvoya.com exactly: Libre Franklin, 17px / 1.7, rgb(247 249 252) ground, rgb(30 43 65) ink, 1080px container.

Closes cvoya-com/web#12.

Closing — redundant, and based on a stale branch point.

This work was already done and merged on main by #1 ("Bring oss.cvoya.com onto cvoya.com's brand system") and #2 ("Remove the 'Hosted service at spring.voyage' claim"). I built this from a shallow clone whose main was two commits behind, so I recreated changes that already existed.

main is in fact ahead of what this PR proposed: it carries full token parity with cvoya.com (--ground, --surface, --ink/--ink-bright/--ink-muted, --site-max: 1080px, Libre Franklin) and the navy band and footer, which this PR did not have. Merging it would have been a regression.

No action needed here. cvoya-com/web#12 is already satisfied by main.
