Origination Series
Warmth Threads
Five distinct takes on one idea: give every Tend contact a warm thread of past touches, so you remember who someone is before you triage them. Generated autonomously from the OG master prompt below.
Master Prompt
AUTONOMOUS ORIGINATION ROUND — "Warmth Threads" for Tend.
You are spawning 5 parallel Builder agents. Each builds ONE standalone variant of the SAME feature: Warmth Threads. This is NOT 5 features — it is 5 distinct design/interaction interpretations of one idea.
THE FEATURE — Warmth Threads:
Tend is a mobile-only "relationship inbox": contacts are unread messages ranked by relational debt (days-since-touch × how much they matter), triaged with swipe-to-log/snooze verbs. v1 nailed the unread badge and the triage verb but stopped at the TOP of the thread — it tells you a relationship is 9 days quiet and worth $40k, but never what was said, promised, or shared. That's the cold-spreadsheet failure mode Tend exists to fight. Warmth Threads adds the missing half of the email metaphor: the conversation history underneath the unread line. Each person-card can reveal a warm vertical thread of past touches — calls, notes, meetings, and especially PERSONAL moments ("Kid's piano recital — wished her luck", "Closed the renewal over coffee — she brought her dog") — so that before you triage someone, you remember who they actually are. It is the mirror image of debt: one face is "what you owe," the other is "why they matter." Personal/human memories must visually glow WARMER than transactional ones. The relationship's age should be stated as a kept thing, not a metric ("You've tended Maria for 14 months").
TEND CONTEXT & HARD CONSTRAINTS (every variant must obey):
- Mobile-only. Exactly 375px wide × 720px tall. Design only for that viewport.
- Pure HTML + CSS. NO JavaScript whatsoever. All interaction via CSS checkbox/radio + :checked sibling selectors, :target, :hover, max-height/transform transitions, scroll-snap. Author honest static proof states (e.g., one card pre-expanded) since there's no JS.
- Warm palette — scope ALL CSS variables to .tnd-app, NOT :root. Reuse verbatim:
--bg:#faf7f2; --bg2:#f4eee4; --card:#fffdf9; --ink:#2b2622; --ink2:#6f675e; --ink3:#9b9288; --line:#ece4d7;
--cold:#6b8cae; --warm:#e0a23b; --urgent:#e06a5b; --green:#3da06b; --accent:#2f9e8f; --accent-soft:#dff0ed;
- Fonts: 'Fraunces' (warm serif display, for dates/names/emotional lines) + 'Inter' (body/UI) via Google Fonts.
- Reuse the existing inbox feel: a sticky header with pressure context, a debt-ranked feed of person-cards (heat edge, monogram, one context line, debt line), a thumb-zone triage verb. The triage verb must stay reachable while a thread is open.
- Touch glyphs for thread entries: ☎ call · ✉ note · ◆ meeting · ♡ personal. Personal entries get the warm/amber treatment and rise visually above transactional ones.
- End each expanded thread with the relationship-age line in sage/green Fraunces.
DELIVERABLE per builder: a single self-contained HTML file with all CSS inline in a <style> block, wrapped in a .tnd-app container, fitting 375×720. It must look like native Tend, not a generic timeline. Each builder receives a DISTINCT angle (below) and must commit fully to that interpretation so the 5 variants read as genuinely different products of the same idea — not reskins.

Research Context
Warmth Threads adds the missing half of Tend's email metaphor: the conversation history beneath the unread/debt line — calls, notes, meetings, and especially personal moments — so you remember who a contact actually is before you triage them. It is the mirror of relational debt: one face is what you owe, the other is why they matter.
Three feature directions were scouted in parallel before this one was chosen:
Three feature directions were scouted in parallel before this one was chosen:
- The Drift Tide — A proactive forecast band that surfaces relationships about to go "unread" — predicting tomorrow's debt today so you tend a few warm ones before they ever turn red.
- The Daily Round — A once-a-day, five-card "tending ritual" that deals you a fixed hand each morning and ends in a streak-keeping closing card — turning relationship upkeep into a brushing-your-teeth habit instead of an open-ended chore.
- Warmth Threads — A pull-down "memory" face on each person-card that replays the relationship's warm moments as a vertical thread of past touches — so before you triage someone, you remember who they actually are.
Variants
v1
Pull-Down Thread
The thread lives INSIDE the card and grows downward in place via a checkbox toggle — the card expands to ~3x height, pushing the feed below it, exactly mirroring the diff-flip pattern. The thread is an accordion that belongs to the card.
v2
Thread Flip
The thread is the BACK of the card — a 3D flip reveals it. The debt face and the warmth face are literally two sides of the same object, reinforcing 'what you owe' vs 'why they matter' as one card with two faces.
v3
Memory Lane
Full-screen immersive thread via :target — tapping a card slides up a dedicated full-bleed 375×720 'memory view' for that one person, an emotional reading room rather than an inline accordion. Big typography, generous whitespace, scroll-through reminiscence.
v4
Warmth Ledger
Reframes the thread as a two-column 'balance sheet of the relationship' — warm/personal memories on one rail, transactional touches on another — so the thread literally visualizes warmth-vs-business balance. Data-aware but humane.
v5
Keepsake Stack
Memories are physical keepsakes — a peelable stack of layered note-cards / polaroids that fan out when opened, with slight rotations, paper texture, and tape. The thread feels like opening a shoebox of mementos, not scrolling a feed.
