Roll out hero media to lessons (pilot + cross-module)#123
Merged
Conversation
Place a captioned hero media block immediately after the TOC on each
lesson, surfacing the lesson's climax demo as an opening hook. Follows
the established pattern: descriptive iframe title / video aria-label,
rotating forward-framing caption openers, and `{: .fs-1 }` captions.
Pilot (12): cpx/{analog-input,button-piano,capacitive-touch,cpx-keyboard,
cpx-mouse,digital-input,makecode,sensor-instrument};
communication/{p5js-serial-io,p5js-serial,serial-intro,web-serial}.
Rollout (11): electronics/{electricity-basics,schematics,ohms-law};
arduino/{arduino-ide,rgb-led-fade,tone}; sensors/{hall-effect,
photoresistors}; esp32/{led-blink,tone,iot}.
esp32/led-blink relocates its workbench video up (removes the lower
copy); others duplicate where the source lives far down as a payoff.
Pages with only generic/placeholder media (arduino/inside-arduino,
advancedio/servo, esp32/capacitive-touch) were intentionally skipped
and are tracked for media completion in #122.

Hero-first:
TOC ---→ hero → optional "what you'll learn" note → prose. Duplicate vs. relocate by distance — relocate (remove lower copy) when the source sits right under the first heading; duplicate when the original lives far down as a genuine preview→payoff.Intentionally skipped (tracked in #122)
arduino/inside-arduino,advancedio/servo,esp32/capacitive-touchhave only generic/placeholder media and need new media before they get a hero.Notes for review
