Switch the site to the light "Papier & Gold" palette

Requested: make the site lighter, the way the colours were originally.
Taken from the house palette "Papier & Gold" (warm off-white, gold as
the only accent): papier #FCFAF6, papier-2 #F4EFE4, card #FFFDF8, ink
#1C1813, quiet #6B6154.

Gold needs more than one hex value. The old dark theme used a single
light gold for both text and fills, which works on a dark ground but
breaks on paper: #C9A461 as text scores 2.25:1. So primary and accent
are now the dark gold #7A5D1F, which carries fill *and* type (5.90:1 on
paper, and takes cream text on top), with #FFFDF8 as its contrast.
googleBlue became Google's actual link blue so the search mock stays
readable on a light ground. Fonts untouched.

Fixed a pre-existing bug this exposed: ".nav-links a" also matched the
header CTA and overrode .btn-primary's colour, so the button rendered
muted text on the primary fill - 1.01:1, effectively invisible. It just
never showed on the dark theme, where both tones were light. Narrowed
to ".nav-links ul a", matching the :hover rule right below it.

Rebuilt the logo as a transparent PNG: logo.jpg had the old dark
background baked in and sat on the page as a black box, with its
"WEBDESIGN" label in light grey that disappears on paper. The pill is
preserved pixel for pixel (row-wise fill so the dark lettering inside
stays opaque, then eroded 1px to drop the old anti-aliasing halo); the
label is recoloured to ink. logo.jpg is kept.

Verified in the browser across all three pages: 228 rendered text
elements measured, 0 WCAG AA failures, tightest pair 5.82 - which is
exactly the documented figure for "quiet on paper". No horizontal
scroll, no console errors.
