"""Lo-fi wave~reader theme (page-blue bg, ink-blue IBM Plex Mono).

One CSS string for the single-page app: instrument-panel blocks on the
#eef6fd page, pill chips (engines / days / badges / skills), left-set
type everywhere. Identity note: the mono face changed from Courier New
to IBM Plex Mono (self-hosted font via Google Fonts, Courier fallback
when offline) — same ink, more designed.
