THUNDERA (proposed light)warm-brown TVs on cream
The whole hero concept is built on dark. 12 warm-brown CRT cabinets are supposed to read as "tuning in late at night, glow from the screens lighting the room." That's why the bezel has the lifted top highlight, why each cell ships scanlines + per-screen vignette, why the chyron title carries an 18px gold text-shadow glow, why the wall vignette darkens the corners, why the Phase 3 hover state spills 60px of warm-white glow onto the wall. On bone all of that goes the wrong direction. The bezels become wooden boxes sitting on a beige carpet. The scanlines become noise on cream. The gold chyron glow has nothing to glow against. The Phase 1 video reveal across all 12 sets and the wall-flash transition into Phase 3 both lose their CRT-lighting-a-dark-room payoff entirely.

THUNDERA (light)white tiles on bone
This is the one surface where light mode works. Toy photography is already cut out on white — tiles dissolve into the bone ground cleanly. But the locked direction called for mondoshop.com's dark editorial premium aesthetic; in light mode it stops feeling like a curated gallery and starts feeling like a retailer product grid. Some upside (cleaner contrast on stat labels), real downside on perceived value.

THUNDERA (proposed)portrait floats with cropped edges
The portrait is the problem. The Lion-O hero portrait was painted with the surrounding painted background as part of the composition — on dark it bleeds into the page, on light you can see the rectangular crop boundary clearly. Multiply that across 118 character entries, plus vehicles and locations, all sourced from production art that assumed dark display contexts. Reference cels in the gallery were drawn for CRT broadcast — they lose contrast on cream because the colourists assumed dark surroundings.

THUNDERA (proposed)cels read as detached postage stamps
Cels were graded for broadcast on dark CRT. The colour palette assumes a dark surrounding context — bright primaries pop, shadows recede. On bone, each cel becomes a small bright rectangle floating on cream, like postage stamps in an album. The grid identity (the TV-wall theme that runs from the homepage into the cels grid) breaks visually because the cels stop being windows into the show and start being thumbnails on a page.

THUNDERA (proposed)black rectangle floats on cream
This is the revenue surface, and this is the worst case. Retailer-supplied promo images (Super7, BBTS, Mattel, Entertainment Earth) ship with black or very dark backgrounds as the de facto industry convention. On dark, they bleed into the page seamlessly — the headline lands on the gradient, the eye flows to the CTA. On light, every news post hero becomes a hard black rectangle floating on bone with a visible edge. Nine posts published with this pattern, every Wave 13/14/15 / drop / giveaway post going forward will have the same problem. Re-cropping every hero by hand on both WP (live) and Astro (dev) doubles the news-post skill workload forever.

Recommendation
Of seven identity-loaded surfaces, only one (toy archive) actually survives a flip to light cleanly, and even there you lose the locked premium feel. The other six degrade somewhere between visible and broken, and the news post hero degrades on your revenue surface specifically.
The version of this idea worth shipping is an accent-only faction toggle — ground stays warm-dark always, but the accent layer rotates between four factions: Mumm-Ra default (current omens-red + amber-bronze + mumm-green), Thundera (sword-gold + heroic blue + bone), Plun-Darr (omens-red dominant + cardboard amber + wine), Berbils (warm woodgrain + workshop teal + cheetara-orange). Same on-brand fan engagement, no image-grading problem, no revenue surface hit, no doubled QA burden on every future news post, character entry, and screengrab batch.
Parked exploration only — not for the current sprint. Open for review and later consideration.
