Blueprint: end_date format changed from 'Y-m-d H:i' to 'Y-m-d' — the
demo frontmatter stores dates without a time component so Admin was
failing to parse it and showing the field empty.
Template: three-case smart range formatting:
- Same month & year → 01 – 03 Sep 2025
- Same year only → 01 Jan – 03 Sep 2025
- Different years → 01 Jan 2025 – 03 Feb 2026

Blueprint: renamed 'Date' to 'Start Date', added optional 'End Date'
field (header.end_date) so it's editable in Admin.
Template: single date → 'd M Y'; range → 'd M Y – d M Y' (full year
on both sides — the old format silently dropped the start year).

Replaced IntersectionObserver (discrete threshold) with a scroll RAF loop
using getBoundingClientRect. Opacity is computed from the fraction of
.story-hero__content still visible above the viewport top — so the nav title
fades in gradually as the hero title slides off the top edge, reaching full
opacity only when the element is completely gone.
Removed CSS transition (no longer needed; per-frame JS update is smooth).

Was visible on load because story-hero__content starts below the
viewport fold (bottom:18% of 140vh hero) — IO fired immediately
as 'not intersecting'. Fixed with hasBeenVisible flag: nav title
only appears after the element has entered then exited the viewport.
Typography changed from DM Sans/500 to DM Serif Display/400 at
--text-lg (1.375rem) with -0.01em tracking — same face as the
hero title, scaled down for the 60px nav bar.

Nav title: absolutely centered in the site-header, fades in via
IntersectionObserver when .story-hero__content scrolls above the fold.
Hidden on mobile (< 640px) where there is no room.
Back-to-top: fixed bottom-right pill, appears after 80% of the hero
viewport is scrolled past, smooth-scrolls to top on click.

Overlay previously hard-hid with display:none when scrollY = 100vh, while
the title was still visible (it exits at ~115vh). Now fades in 0→0.65 over
the first 70vh then fades back out to 0 by 140vh (full hero height).
Scrolly caption changed from full-width to centered pill with
rgba(0,0,0,0.45) background — readable against any image regardless of tone.
