Frontend pass on the two embedded HTML templates in the FastAPI server. No
backend / Python logic changed; only template strings, CSS, and inline JS.
Index page: full CSS custom-property theme (light, #c39733 accent),
responsive viewport meta, search input with embedded SVG magnifier and
focus ring, control bar reorganised into divider-separated groups with
the browse-mode toggle rendered via :has() selector, hit cards with
hover-lift + arrow indicator and focus-visible outline, restyled Q/A
badges and score/topic chips, animated loading dots.
Episode page: sticky audio player and sticky aside (top: 130px,
max-height calc'd against viewport). New active-Q&A highlight builds a
sorted index of QA blocks at load time, computes each block's end as
the next block's start (capped at +180s), and on timeupdate/pause
toggles .active on both the body QA block and its aside list item; a
"NOW PLAYING" pill is revealed on .qa.active. Intro-marker also gets
.active. Audio preload bumped from none to metadata so #qa-<id> deep
links can seek without a prior user gesture.
