feat(web): honest, state-aware summarize status with charm spinner (ADR-025)

Clicking Summarize polled /status, which knew only "spinning" or "done". The web
ProcessVideo recorded an outcome only on success, so a 429'd or caption-less
click left transcript_status unset and the poll silently reverted to the
Summarize button — the rate limit was invisible and the click felt broken.

- ProcessVideo now records rate_limited / none / fetched (mirrors the runner); a
  rate-limited video keeps its requested flag so the background sweep retries it.
- /status is state-aware: summary card (done), working spinner (in-flight),
  a calm "waiting on rate limit, will retry" card that keeps polling so the
  summary lands on its own (no re-click), and a terminal "no captions" card.
- Charm status text (Claude-Code / Crush inspired): the spinner cycles playful
  tapir-themed gerunds via CSS only (no JS), decorative + an sr-only stable
  status line for a11y.

Pillar A (foreground fetch priority lane) is a separate follow-up.

+## ADR-023 — Drop Shorts/livestreams at discovery to protect the caption budget
+
+**Status:** Accepted (2026-06-10). **Builds on ADR-014** (per-IP caption rate limit is the
+binding constraint) and the ADR-022 live-run findings.
+
+**Context.** The scarce resource is the unofficial timedtext caption fetch (per-egress-IP
+429, ~3 successful/pass). The first multi-user run showed the candidate set was mostly noise —
+Shorts, sub-minute clips, and live broadcasts — each of which still consumes a caption-fetch
+attempt (and a "none" result is a *completed* fetch, so it costs budget even when it yields
+nothing). Spending the rate-limited budget on content the user will not read is the waste to
+cut first; it is cheaper and lower-risk than raising the ceiling (multi-IP, Whisper).
+
+Duration and live status are NOT in the playlistItems discovery response, but they ARE in the
+Data API `videos.list` (contentDetails.duration + snippet.liveBroadcastContent) — the official
+**quota-based** API (1 unit/call, 50 ids/call), which is a *different* limit from the timedtext
+429. So one cheap quota call buys a filter that saves many expensive throttled fetches.
+
+**Decision.**
+1. `NewVideos` enriches its candidates with a single `videos.list` call and drops, before
+   returning: videos shorter than `TAPIR_MIN_VIDEO_SECONDS` (default 60) and any `live`/
+   `upcoming` broadcast. Dropped videos are never persisted, so they also declutter the list.
+2. The filter is **degrade-open**: `MinVideoSeconds=0` disables it (no quota call), and a
+   `videos.list` error returns the candidates unfiltered — discovery must never break because a
+   metadata call hiccuped (worst case = pre-ADR-023 behaviour).
+3. The paste-a-URL path (`VideoByID`) is **not** filtered — an explicit user request for a
+   specific video (even a Short) is honoured.
+
+**Reversibility.** Pure discovery-time filter + config. `TAPIR_MIN_VIDEO_SECONDS=0` restores
+the old behaviour. No schema change, no effect on already-stored videos.
+
+**Quota note.** Per-channel enrichment adds ~1 unit/channel/pass. At pilot scale (≤3 users)
+this is well under the 10k/day cap; at larger scale, batch `videos.list` across channels
+(50 ids/call) by collecting all discovered ids per pass before enriching.
+
+---
+
+## ADR-024 — Per-channel caption-availability memory
+
+**Status:** Accepted (2026-06-10). **Builds on ADR-014** (per-IP caption budget), **ADR-021**
+(shared transcript cache), **ADR-023** (Shorts filter).
+
+**Context.** After ADR-021 caches transcripts and ADR-023 drops Shorts, the remaining caption
+waste is the *first* fetch on every new video of a channel that never publishes English captions
+(foreign-language news, music, etc.). Each costs one rate-limited fetch to resolve to "none" —
+and on a throttled IP that fetch may 429 and churn the backoff machinery before it ever gets a
+verdict. A pilot user's feed had several such channels.
+
+**Decision.** Remember, per `(user, channel)`, a streak of consecutive no-caption outcomes
+(`channel_caption_state`, migration 016, RLS-scoped like the rest of the user-owned schema).
+Once the streak reaches `TAPIR_CHANNEL_CAPTIONLESS_THRESHOLD` (default 5) the channel is
+suppressed — its videos are discovered/listed but not caption-fetched — for
+`TAPIR_CHANNEL_CAPTIONLESS_WINDOW` (default 14d), after which one video is re-probed
+(auto-recovery for a channel that starts adding captions). A successful fetch resets the streak;
+a fresh 429 does NOT count (transient, not a caption verdict). An explicit manual request
+bypasses suppression. `threshold = 0` disables the feature.
+
+**Why per-user, not global.** Caption availability is really a channel property (public), so a
+global table would let users share the learning. But subscriptions are per-user (ADR-012) and at
+pilot scale users' channel sets barely overlap, so per-user + RLS keeps it consistent with the
+existing isolation model with no new non-RLS exception to justify. Promoting to a shared table
+(like transcripts, ADR-021) is a future optimisation if channel overlap grows.
+
+**Reversibility.** Migration 016 is a clean drop; `threshold = 0` disables at runtime. The
+memory only ever *suppresses fetches* — it never deletes content or affects already-stored
+summaries.
+
+---
+
+## ADR-025 — Honest, state-aware foreground summarization status
+
+**Status:** Accepted (2026-06-10). **Pillar B of the manual-mode UX work** (Pillar A, foreground
+fetch priority, is a separate follow-up). Builds on ADR-014 (the rate limit the UX must make
+legible).
+
+**Context.** Clicking "Summarize" spawned a background goroutine and polled `/status`, which
+returned only two states: the spinner (in-flight) or the normal card (done). But the web
+`ProcessVideo` only recorded an outcome on *success* — a 429'd or caption-less click left
+`transcript_status` unset, so the next poll silently reverted to the "Summarize" button. The
+user saw either an endless spinner or a button that did nothing useful when clicked again. The
+binding constraint (YouTube's caption rate limit) was completely invisible.
+
+**Decision.**
+1. **Record every outcome on the web path**, mirroring the runner: `ProcessVideo` stamps
+   `rate_limited` / `none` / `fetched`. A rate-limited video keeps its requested flag so the
+   background sweep retries it; `none` and `fetched` are terminal.
+2. **`/status` is state-aware**: summarized → summary card; in-flight → working spinner;
+   `rate_limited` → a calm "waiting, will retry" card that keeps polling (every 30s) so the
+   summary appears on its own when the retry lands — the user never clicks again;
+   `none` → a terminal "no captions" card with no poll and no dead-end button.
+3. **Charm status text** (Claude-Code / Crush inspired): the working spinner cycles playful,
+   tapir-themed gerunds ("Chewing the cud…", "Munching leaves…", "Distilling the gist…") via
+   CSS only — no JS, keeping the HTMX/no-JS ethos. Decorative (aria-hidden) with a stable
+   `role=status` line for assistive tech.
+
+**Principle.** When the system cannot be fast (throttled IP), it is at least honest, and it
+self-resolves without making the user retry. Honesty is the load-bearing half — Pillar A's
+priority lane only improves the odds of a fast slot; it cannot beat an already-hot IP.
+
+**Reversibility.** Pure transport-layer + view change over the unchanged engine/ports. No
+schema change (reuses `transcript_status` from migration 007).

+-- (ADR-014) before resolving to "none" — and on a throttled egress IP that fetch

+-- it to 0. Once it crosses the threshold the channel is suppressed until
+-- captionless_until, after which one video is re-probed (auto-recovery for a
+-- channel that starts adding captions). Per-user + RLS-scoped, consistent with
