Asks on a phone: full-width rows, one-thumb actions, and the pull says what it removed #1062

Replaces #691, parked twice:

• the check failed ("capacity: only a forge admin reads or changes it > an admin changes each one from the page, the API and MCP; a wrong value is refused; every change is kept") and the decider saw no point in another try (pull #1002 closed). Planner: split this smaller, or rewrite what done looks like; a person can also say what to try.
• the check failed ("capacity: only a forge admin reads or changes it > an admin changes each one from the page, the API and MCP; a wrong value is refused; every change is kept") and the decider saw no point in another try (pull #1031 closed).

Those checks went red on tests this change does not touch. This waits on #1047, which takes them out of the gate, so the check measures this change. Start from today's main. What done looks like is #691's, unchanged:

Pillar: P1 Feed (umbrella #587). Applies to the survivor #634 leaves (the pinned "needs you"). One run, after #634.

Why. Owner, 2026-10-05: "the UI leaves a lot of white space on mobile."

The job: decide asks with one thumb on a phone.

Acceptance.

• [ ] At 390 px wide, rows use the full width: no card margin inside a page margin, a 16 px gutter at most, the title wraps instead of truncating, and the repository name sits on the same line as the kind.
• [ ] The primary action of each row is reachable with one thumb (at the row's trailing edge or a swipe), at least 44 px tall; secondary actions sit behind one tap.
• [ ] The pull says what it removed to make room: for example nested card padding, the per-row icon column, the repeated "green, waiting for your look" sentence.
• [ ] Desktop does not regress: the same rows at 1280 px.
• [ ] Reachable: the page; looks at 390 px and 1280 px on the pull, before and after; the full check green.

Start from: src/web/studio/asks_page.ts (or the survivor #634 leaves), src/web/studio/feed_style.ts, src/web/ui.ts.

Must not touch: the release workflow, the chart, other repositories.

Parked by the crew: the check failed ("asks that earn their place > five rows by default, the rest one tap away; a phone shows two (#883)") and the decider saw no point in another try (pull #1373 closed). Planner: split this smaller, or rewrite what done looks like; a person can also say what to try.
