🛍️ Rewards store: big image on tap + insufficient-points / TinaCMS store message

[jernejk]

Requested by Adam Cogan — email "Rewards - store" (16 May 2026, V2 adding Josh). cc: Tiago Araujo, Josh Berman.

The Rewards store / redeem screen needs the following tweaks (see screenshot below).

Requirements

1. ✅ Rename "Llama Plushie" → TinaCMS Plushie — done
2. ✅ "mug" should not be uppercase (e.g. "TinaCMS Mug", not "TinaCMS MUG") — done
3. ⏳ When you tap a reward record, show the big image — in progress
4. ⏳ When you tap a reward you can't afford it currently does nothing — instead it should say either:
   • "You need xxx more points", or
   • "Purchase at the TinaCMS store" (tappable link) — in progress

Notes

• The TinaCMS store URL still needs to come from Tiago — it's currently a placeholder/empty constant, so the link path is wired up but not yet live.
• Items 3–4 are being implemented on branch codex/reward-tap-details.

Screenshot

⚠️ Attach store-rewards-list.png here (the TinaCMS shirts / tote / mug / plushie list). The GitHub CLI can't upload images, so it needs to be dragged into the issue.

Draft PR opened: #1561

Evidence and the local delivery folder are at /Users/jk/Developer/clients/ssw/work/rewards-1560-store-tap-details/.

Notes:

• Items 3-4 are implemented and verified with before/after emulator screenshots.
• ⚠️ TODO: Ask Tiago for TinaCMS store #1557 tracks the missing TinaCMS store URL from Tiago; until that URL is provided, the store prompt is visible but not a live external link.
