feat(pitch): re-time the deck to the recorded narration beats (2:12)#89
Conversation
The generated 1.2x narration (109.8s) was much shorter than the deck (188s) and its
per-frame holds were misaligned with the beats (F4 hero held 25s for a 2s line; F5
held 6s for a 12.5s line). Rather than pad the narration with dead air, I split the
real audio at its silence boundaries (ffmpeg) and re-timed the deck to those clip
lengths + a short visual tail.
- SLIDE_DURATION -> [5,18,8,8,5,14,12,13,9,22,9,9,12] (cover->F11 = 132s / 2:12).
- F5 fixed (6s -> 14s so its VO fits); F4 hero 25s -> 5s (clip 2s + dramatic hold).
- All "188s" labels -> "2:12" (title, cover meta, cover-cta, F-key button, playRange,
JS comment); cover "0:35-1:00 -> 0:34-0:39" F4 chip; close stat number dropped
("One run. One audited score.").
- Comment notes F8-F9 are replaced by a live /participate screen-recording in the
final cut (so the delivered video is ~2:30-2:50); the array keeps them for a
slides-only fallback.
Verified in browser: SLIDE_DURATION 13 elements summing to 2:12, cover meta renders
"2:12 · runtime", no "188" left, no console errors.

Code Review
This pull request updates the presentation deck's total runtime from 188 seconds to 2:12 and adjusts individual slide durations in the SLIDE_DURATION array. The review feedback points out two main inconsistencies introduced by these changes: first, the hardcoded slide timestamps in the HTML markup (e.g., <span class="time">) are now out of sync with the updated slide durations; second, the opening range (F1 to F4) duration is still hardcoded as "60s" in multiple UI elements and event handlers, whereas the new cumulative duration is 39 seconds.

The hardcoded presentation timestamps in the topbar of each slide (e.g., <span class="time">0:00 – 0:10</span> on Slide 2, <span class="time">0:35 – 1:00</span> on Slide 5, etc.) are now completely out of sync with the newly updated SLIDE_DURATION array.
For example, based on the new durations:
- F1 should be
0:05 – 0:23(instead of0:00 – 0:10) - F2 should be
0:23 – 0:31(instead of0:10 – 0:25) - F3 should be
0:31 – 0:39(instead of0:25 – 0:35) - F4 should be
0:39 – 0:44(instead of0:35 – 1:00) - F5 should be
0:44 – 0:58(instead of1:00 – 1:06) - ... and so on.
Please update the <span class="time"> elements inside the <section class="slide"> containers for slides 2 through 12 to match these new cumulative timings so that the displayed slide timestamps are accurate and consistent with the actual auto-advance durations.

The duration for the opening range (F1 to F4) is still hardcoded as 60s in several places, but according to the new SLIDE_DURATION array, the actual duration is now 39 seconds (18 + 8 + 8 + 5).
Please update the following references to reflect the new 39s duration:
- Line 1260:
<button id="btn-play-opening" ...><span>▶ Opening · F1→F4 (60s)</span>...-> change(60s)to(39s) - Line 1638:
playRange(1, 4, 'opening · F1 → F4 · 60s')-> change60sto39s - Line 1665:
playRange(1, 4, 'opening · F1 → F4 · 60s')-> change60sto39s
Per the user's call: keep the generated 1.2x narration (109.8s), split it at its silence boundaries, and re-time the deck to those real clip lengths instead of padding the narration with dead air.
